Have nations ever just lopped off a part of themselves

As in, decided they didn’t want to retain a particular part of their territory and just ignored it. Not selling it like Russia and France did with territory in North America, or agreeing to hand it over like many European nations did around the two world wars, or allowing it to volunteer for independence. Just saying to everyone in general, no longer a part of our nation, not our territory.

Something like the Western Sahara I suppose. Given up by Spain, not really a part of any other country, with another nation assuming control over it.

Malaysia expelled Singapore back in 1965.

There’s Bir Tawil that neither Egypt nor Sudan wants (because they’d rather have the Hala’ib Triangle and claiming one means they can’t claim the other).

Portugal walked out of East Timor in 1975 after 200 years of occupation. Their independence lasted a whole two weeks, when Indonesia invaded.

South Africa tried to declaim responsibility for some of the worst slums by declaring them independent.

The Czech Republic and Slovakia split by mutual agreement.

Jordan unilaterally renounced all claims to the West Bank in 1988 (although it had already sorta kinda given it to the PLO at the '74 Arab League Summit).

Not exactly what the OP asked for, but Austria was excluded from the formation of the German Empire in 1871, after losing the war against Prussia a few years prior.

Also, I don’t know if that’s true, but allegedly, Belarus wants to unite with Russia, but the Russians don’t want them.

Are you referring to the bantustans? That’s a good example of for the OP, but you have kind of a strange interpretation of the events.

Basically, white South Africa started to get very uncomfortable with having a black majority, so they came up with a clever plan to disenfranchise black people- why not just revoke their citizenship? You don’t have to protect the rights of non-citizens, after all, and they can never vote against you. Easy-peasy.

So a haphazard splatter of “black homelands” were designated, made out of all kinds of specks of land like so many scattered islands. They were declared independent, and a bunch of people suddenly found themselves no longer citizens of their own country. Instead they might be declared citizens of an often distant place they may not have ever even visited. These areas took up 13% of the country, leaving the rest of South Africa nice and legally white.

The big plan was to eventually corral all of the black people in the homelands, leaving the rest of South Africa sparse and free for whites to do whatever. But in reality, most people stayed put and worked as “guest workers,” with no political participation, few rights, and little protection.

Australia became independent from Britain.

Britain and Australia let , encouraged , Papua New Guinea to become independent and unite.

Of course there were also Dutch , Portuguese, Spanish in Asia.

Events in Cuba caused Spain to hand over the Phillipines to the USA.

Events in India causes Britain to walk away.

Argentinia pretended to walk away from the Falkland Islands, they really thought it a smart political move, they could then claim to be the underdog in the war to reclaim them. Well no scratch that, you can’t find reasons for being really weird.

If we’re talking about granting independence, then every country that had a colony nation has given up the territory. Some African colonies became independent through revolution, but in the 1960s, the European nations were leaving the colonies at the slightest indication they wanted to be free.

But those are colonies, not part of the original country. However, both Ireland and Algeria were considered integral parts the UK and France, respectively. Both became independent because of national independence movements, though.

Israel “disengaged” from he Gaza Strip, unilaterally, in 2005.

The US essentially gave up Cuba in 1902 to form its own nation.

The Hudsons Bay Company gave its territory to Canada.

HBC wasn’t a nation; it was a commercial trading company. Its claim to Rupert’s Land was by virtue of a royal charter, but the lands remained under the sovereignty of the Crown.

Nor did it give its territory to Canada. In return for £300,000 from Canada, the HBC surrendered its claim to the lands back to the Crown. The Crown then granted the lands to Canada, under s. 146 of the British North America Act, 1867.

Never was annexed to begin with – merely occupied. The Treaty that ended the Spanish-American War provided that the Phillipines, Guam and Puerto Rico were surrendered to US sovereignty, but Cuba was to become independent (the Filipinos were rather ticked off this was not done for them too).

There ius a dispute between Egypt and Su8dan over precisely where the border between their contries lies. The dispute leaves an area that both claim ownership of. There’s also another area that Egypt says Sudan owns, and Suidan says Egypt owns.

edit - just noticed post#3.

That was all based on McKinley’s good intentions. He was more or less an okay guy (very relative term when discussing American politicians from the second half of the 19th century) who was lead into war by a strong contingent of war hawk imperialists who had a big loudspeaker serving their interests in the form of yellow journalism. Anyway, McKinley actually bought the argument that Spain was an evil task master and it was America’s responsibility to address those wrongs. The Maine gave it all the last push it needed.

Come peace time a lot of the guys who helped push McKinley into war wanted to keep basically Cuba and eventually make it a State while making the rest of the possessions colonies. McKinley looked at the situation and determined the Cubans were sufficiently advanced that they should be independent, and he determined the rest of the territories were not. This ticked off some of the business interests who mostly were just interested in potential money to be made in Cuba and not Cuban political rights. Of course in the end they did make their money in Cuba as American investments were handled very favorably until Castro.

The Filipinos fought an extremely violent struggle against us for independence and lost. I’ve actually often pointed out that 100 years from now the Iraq war for all its controversy will not be significantly remembered. Far more people died (on our side and on the other) in the Philippines and it’s essentially a wholly forgotten conflict now by anyone but students of history.

Make Cuba a state?! Not challenging, just amazed. Even New Mexico or Texas vis-a-vis Mexicans was not so completely culturally empty of Anglos, let alone New England, where obviously different political forces were at pay.

Correct me where I’m wrong by being so shocked.

Remember we did similar stuff in Hawaii not long before. American business interests got us involved there and eventually we basically took it as a territory. I’m not saying people were pushing for Cuba to be a State in 1900, just that it was seen as land we needed to grab and take permanently. As far back as the 1820s there had been Americans scheming to take Cuba, I don’t think Statehood was seen as the immediate goal but would have been understood for a large populated island right next to us…especially as statehood adds permanence. Jefferson spoke directly of Cuba as being a desirable addition to the United States. Hawaii was no more Anglo than Cuba when we started getting involved there, so that concern is probably not a big one.

I got my timeline a little mixed up though, the Cuba as a State argument was actually made prior to the War why they hashed out how we’d govern Spain’s territory once we beat them. Many in McKinley’s circle that had pushed for war wanted to annex Cuba, but McKinley ultimately went along with the Teller Amendment which prohibited using military force to annex Cuba and made a guarantee of seeking Cuban political self determination.
