Well things have already been a tad rough around this square, so if we follow the trend, the next square might turn bad even sooner. So maybe around, I dunno, 2101?
1225: ten years earlier, Magna Carta starting to limit monarchs and the seed of individual freedom
1681: eight years later was glorious revolution with a bill of rights, marking individual freedoms
1764: ten years later, beginning of American Revolution and being free of monarchs
1849: ten years-ish later, start of US civil war; was the time of an attempt by the British to end slavery around the world
1936: ten years later, colonial empires were being dismantled, UN established to attempt global cooperation, US in the ascendancy with a seed of ties being established more by economics than military force, great economic upswing lifting people out of poverty (60% in poverty then, 10% now) while the global population blossoms
2035: Majority of the global population in middle class or better, triumph of individuals over technocrats, bureaucrats, and corporatists :)
