Three Gorges Dam
EnergyThe world's largest hydropower station by installed capacity, at 22.5 GW, and the main flood-control structure on the Yangtze.
Part of the Norwegian Kingdom of the Hebrides until the 13th century when it was ceded to Scotland, the isle came under the British crown in 1765. Current concerns include reviving the almost extinct Manx Gaelic language. Isle of Man is a British crown dependency but is not part of the UK or of the European Union. However, the UK Government remains constitutionally responsible for its defense and international representation.
The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.
Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.
Example assets. These twenty cards are modelled on China's most critical infrastructure and show on every nation page until each nation's own assets are mapped.

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where Isle of Man stands, the index says how it arrived there.
Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.
In the later Mesolithic, sea levels rose following the end of the last ice age and severed the Isle of Man from neighbouring landmasses. The island's separation defined its geography and made all subsequent settlement dependent on seafaring.
Humans reached the Isle of Man by boat some time before 6500 BC, after the island had been separated from its neighbours. The first occupants lived by hunting, gathering and fishing, and examples of their tools survive in the Manx Museum. This marks the beginning of continuous human presence on the island.
Strong Irish influence across the Irish Sea in the late Roman period brought Gaelic settlement to Man, and Orosius recorded the island as inhabited by the Irish. Ogham stones, monolingual Irish in the south and bilingual Irish and Latin in the north, attest Archaic Irish as the first recorded language. From this the Goidelic Manx language later developed.
Manx tradition holds that Patrick sent Maughold and Germanus to the island, although Muirchú's seventh-century Life of Patrick suggests a Christian community under Conindrus and Rumilus already existed. More than 200 small chapels, or keeills, were built in the centuries after Christianisation, embedding an ecclesiastical structure across the island.
The island came under Anglo-Saxon Northumbrian control during Edwin's reign, and was used as a base for raids on Ireland. The extent of Northumbrian influence is unclear, and very few Manx place names are of Old English origin, suggesting shallow settlement.
Norse raiding on the Isle of Man began in the late eighth century and was followed by permanent settlement. This opened the Scandinavian era that would reshape the island's rulership, institutions and land divisions.
From around 914 the island was ruled by Norse-Gaelic kings beginning with Ragnall ua Ímair, and became part of the Kingdom of the Isles, or Kingdom of Mann and the Isles. The Norse-Gaelic rulers established Tynwald and introduced land divisions that still exist, giving the island durable governing institutions.
The island's parliament is described as the oldest continuously governing body in the world, with a claimed foundation in 979 or earlier, though evidence supports a later date. The claim is central to Manx constitutional identity and to the island's distinct standing.
A mint operated on the island for roughly four decades in the eleventh century, striking coins from a penny die imported from Dublin. The issue demonstrates Man's integration into the Hiberno-Norse trading and monetary world of the Irish Sea.
From 1079 the island was held, with some interruptions, by the Crovan dynasty. Its capital lay on St Patrick's Isle, where Peel Castle was built, consolidating a recognisable Manx kingdom within the wider Norse world.
Magnus Barefoot was a notable exception to the general Norwegian pattern of loose overlordship, ruling Man directly for four years. Throughout the Scandinavian period Man was a dependency of Norway, but Norwegian kings rarely asserted their control.
The diocese was formed in 1154, giving formal ecclesiastical organisation to Man and the Southern Isles. It provided an institutional structure that outlasted the Norse kingdom itself.
Magnus VI of Norway sold his suzerainty over Man to Alexander III of Scotland in the Treaty of Perth, transferring Norwegian overlordship of the island — part of the Norwegian Kingdom of the Hebrides until the 13th century — to the Scottish Crown. It ended nearly four centuries of Scandinavian dependency and began a long period in which the island was contested between Scotland and England rather than governed as an independent kingdom.
Scottish rule over Man had not been firmly established after the Treaty of Perth until the Manx rising was crushed in 1275. The defeat ended organised local resistance and confirmed Scottish control for a time.
English forces seized the island in 1290, holding it until 1313. This began a period of repeated transfers of the island between the English and Scottish crowns.
Robert the Bruce took the island in 1313 after a five-week siege of Castle Rushen; it was retaken for the English in 1314 by John Bacach of Argyll, for the Scots in 1317 by Thomas Randolph, and held by Scotland until 1333. Control passed back and forth until the English took it for the last time in 1346. The English Crown then delegated rule to a series of lords and magnates.
After alternating Scottish and English rule, Man passed definitively into the feudal lordship of the English Crown in 1399. Tynwald continued to legislate and control finances, but subject to the approval of the Lord of Mann, setting the pattern of internal self-government under external suzerainty.
From 1541 the island's sixteen parishes have formed part of the Province of York. The transfer aligned Manx ecclesiastical governance with the English church settlement.
During the English Civil War the Lord of Mann levied ten men from each of the island's parishes for the Royalist cause. The majority of the 170 died at Wigan Lane in 1651, a heavy loss drawn directly from the island's small population.
The feudal rights of the Dukes of Atholl as Lords of Man were bought out and revested in the British Crown. The island nonetheless did not become part of the Kingdom of Great Britain or its successor states, establishing its enduring status as a Crown dependency outside the United Kingdom.
A fencible regiment was raised in 1779 for home defence and disbanded in 1783 at the end of the American War of Independence. It was the first of several Manx fencible bodies formed during the wars of the period.
A 1st Battalion of three companies was raised in 1793 and a 2nd Battalion of ten companies in 1795, the latter seeing action during the Irish Rebellion of 1798. The regiment was disbanded in 1802.
A third fencible force was raised in 1803 to defend the island during the Napoleonic Wars and to assist the Revenue, and was disbanded in 1811. Throughout the wars Man served as a strategically important but often neglected naval outpost.
Town gas was supplied from 1836, later replaced by liquefied petroleum gas, and natural gas became available from 2003. The sequence marks the island's long transition through successive energy infrastructures.
Founded in 1850, Okells brews on a commercial scale and remains the island's biggest brewer. Its output is governed by the Isle of Man's Brewers' Act 1874, a purity law resembling the German Reinheitsgebot.
From 1866 the House of Keys was partly elected, though the Legislative Council remained appointed by the Crown. Democratic government has been extended gradually since, with most of the Legislative Council now elected by the House of Keys.
The Act restricts brewers to water, malt, sugar and hops, resembling the German Reinheitsgebot. It remains in effect and shapes the island's brewing industry.
Elon Musk's satellite internet service was reported in August 2021 to have received a licence for a Manx ground station. It extended the island's role as a host for international communications infrastructure.
The law prohibiting commercial cultivation of cannabis was repealed in June 2021 and licences for production and export were offered for the first time. In February 2022 billionaire John Whittaker's firm Peel NRE proposed US$136 million of investment in cultivation warmhouses and research facilities.
The 2021 census counted 84,069 residents, of whom 26,677 lived in Douglas, an increase of 755 since 2016. Full censuses have been decennial since 1821, with interim censuses added from 1966.
In January 2020 the island's former Chief Minister formally apologised to gay men convicted under earlier Manx laws. The apology followed decriminalisation in 1992 and signalled a broader shift in official attitudes.
An office of The International Stock Exchange opened in 2017, adding capital-markets infrastructure to the island's offshore financial sector. The finance industry has grown on the back of regulatory arbitrage and low taxes.
In March 2016 the whole of the Isle of Man was adopted as a UNESCO biosphere reserve, the first entire territory to be so designated. The status gave the island distinctive international environmental standing.
The island was never part of the EEC or European Union and held no special status, so it did not take part in the 2016 referendum on UK membership. In 2017 the UK confirmed that the Crown Dependencies' positions were included in the Brexit negotiations.
A new Army Reserve unit was set up in Douglas in 2015. It restored a standing British military training presence on the island decades after the disbandment of the Manx Regiment.
Two space stations owned by Excalibur Almaz arrived in January 2011 and were housed in a hangar at the former RAF Jurby airfield. Together with the X Prize team summit held on the island in October 2010, it reflected Manx efforts to attract space-sector business.
A new fibre-optic cable was commissioned in December 2007, connecting the island directly to global networks. The link underpinned the growth of offshore financial services, e-gaming and digital business.
The 2007 agreement established frameworks for developing the Isle of Man's international identity separate from that of the United Kingdom. It formalised how the Crown dependency projects itself abroad.
On 27 March 2001 the UK ratified the Charter on behalf of the Isle of Man government, recognising Manx as a legitimate autochthonous regional language. The move gave international standing to the revived language.
In 1996 the government secured control of the .im national top-level domain and holds ultimate responsibility for its use. The domain gave the island a distinct presence and a revenue-bearing asset in the digital economy.
Same-sex sexual activity was decriminalised on the island in 1992. In January 2020 former Chief Minister Howard Quayle issued an unqualified apology to men convicted under the previous laws.
The government operated its own lottery from 1986 until 1997. From 2 December 1999 the island instead participated in the United Kingdom National Lottery, and from 2010 Manx projects became eligible for Good Causes funding.
The death in 1974 of the last native Manx speaker marked the end of the language as a community tongue. It prompted a general revival of Manx language and culture, and by the 2011 census around 1,800 residents said they could read, write and speak it.
Responsibility for postal services passed from the British General Post Office to a Manx body in 1973. It was a concrete step in building separate national administrative capacity.
As a British crown dependency the island is not part of the United Kingdom, and when the UK joined the European Community in 1973 the Isle of Man stayed outside the union. The UK Government remains constitutionally responsible for its defence and international representation.
Traditional Manx folk music has undergone a revival since the 1970s, beginning with the Yn Chruinnaght festival. It formed part of a wider reassertion of Manx language and cultural identity.
In 1947 the Irish head of government led an initiative to record and preserve Manx, then close to extinction. The effort helped underpin later revival work on a language closely related to Irish and Scottish Gaelic.
The Manx Regiment existed from 1938 to 1955 as part of the British Territorial Army and fought extensively in the Second World War. It gave the island a distinct military formation within the British forces.
During both world wars people originating from enemy countries were interned on the Isle of Man. The camps made the island a significant instrument of British wartime security policy and temporarily reshaped its population.
The TT began in 1907 and became the main international event associated with the island. In 2025 almost 40,000 tourists attended, spending over £50 million, making it a pillar of the visitor economy.
Built in 1899 and restored to its original splendour in 1976, the government-owned theatre presents plays, musicals, concerts and comedy year-round. It anchors the island's performing arts alongside the adjoining Broadway Cinema.
The 1881 franchise extension enfranchised women for general elections, though married women were excluded. It gave the Isle of Man a world first in representative government and remains central to its political identity.
A railway undertaking was founded in 1876. The island retains a steam railway between Douglas and Port Erin, an electric railway between Douglas and Ramsey, and an electric mountain railway climbing Snaefell.
Part of the Norwegian Kingdom of the Hebrides until the 13th century when it was ceded to Scotland, the isle came under the British crown in 1765. Current concerns include reviving the almost extinct Manx Gaelic language. Isle of Man is a British crown dependency but is not part of the UK or of the European Union. However, the UK Government remains constitutionally responsible for its defense and international representation.

Offshore banking, manufacturing, and tourism are key sectors of the economy. The government offers low taxes and other incentives to high-technology companies and financial institutions to locate on the island; this has paid off in expanding employment opportunities in high-income industries. As a result, agriculture and fishing, once the mainstays of the economy, have declined in their contributions to GDP. The Isle of Man also attracts online gambling sites and the film industry. Trade is mostly with the UK. In January 2013, the Isle of Man signed a tax agreement with Guernsey and Jersey, in order to enable the islands' authorities to end tax avoidance and evasion. The Isle of Man enjoys free access to EU markets.
