After the empires fell

World War I ended an era. Four empires collapsed, borders were redrawn, and new leaders rushed to fill the vacuum. The states they built — and the rivalries between them — would shape global power for the rest of the century.

A world of empires

Before 1914, a handful of empires controlled most of the globe — British, French, German, Russian, Austro-Hungarian, and Ottoman. By 1918, four had collapsed. In their place emerged a patchwork of new nations, many with borders drawn by the victors rather than the people living within them.

Common questions

No, many decolonisation movements were violent. Algeria and Vietnam only won independence after years of guerrilla warfare and brutal crackdowns, while Ghana's transition was negotiated with far less bloodshed. Even relatively calm handovers often followed decades of protest and repression that rarely make it into the history books.

No, decolonisation isn't fully finished. The United Nations still lists 17 non-self-governing territories around the world, including islands in the Caribbean and the Pacific, where full self-government hasn't yet been achieved. Independence movements and debates over colonial-era institutions continue in many former colonies well into the twenty-first century.

Independence is the specific legal moment when a colony's government takes full political control from its coloniser, but decolonisation covers the whole surrounding process. It includes building new institutions and reworking the economic and cultural ties colonial rule left behind, and it often continues long after independence is formally declared.

Colonial rulers often drew borders that ignored existing ethnic and cultural lines and built economies around exporting raw materials rather than developing local industry. New governments inherited these weak, dependent structures along with untested institutions, which fed political instability and economic hardship in the years right after independence.
