Based on some similar threads I can remember, this is a place to share those TL ideas and PODs that you always found really interesting, but never had time to write.
For me: what if the English Levellers were able to take political control over the Commonwealth?
What if Thomas Müntzer had not been captured after the Battle of Frankenhausen and had survived to create a radical new sect of Christianity?
What if the many anarchist/libertarian socialist communes established in the late 19th century (in the United States) had manifested into an actual anarchist political tradition in US politics?
What if the Newburgh Conspiracy had translated into actual political action, leading to a military coup/civil war in the first years of the United States?
What if Mutualism rather than Marxism became the dominant leftist revolutionary tendency in the 19th century?
I've got quite a few more, but I could go on for days. What about you guys?
