In November 1095 Pope Urban II, answering a Byzantine emperor's plea for help against the Seljuk Turks, called western Christians to an armed pilgrimage to Jerusalem. Tens of thousands answered — knights, foot soldiers and poor pilgrims. Their armies took separate roads to Constantinople, then marched together across Anatolia and Syria. Almost four years after the call, they stormed Jerusalem and massacred much of its population.
The route follows the main armies in order, from Clermont to Jerusalem, using the participants' own chronicles as summarised by modern historians. Violence against Jews in the Rhineland and against the people of the cities on the way is part of the story and is named plainly. There are no travel tips for Syria or the Lebanese border area.
In October 1934 the Chinese Communists' main army, beaten by Chiang Kai-shek's Nationalists, broke out of its base in Jiangxi and fled west. A year and some 9,000 kilometres later, after river crossings under fire, snow passes and a high-altitude swamp, a few thousand survivors reached northern Shaanxi. On the way, Mao Zedong rose to lead the party, and the retreat became its founding legend.
The route follows the Central Red Army, the best-known of several Long March columns, in date order. Official histories have polished some episodes, and historians still argue about how much fighting there was at Luding Bridge; the texts note where accounts disagree. Most stops now have memorials and museums.
In the spring of 334 BC Alexander, the 22-year-old king of Macedon, crossed into Asia with an army of Macedonians and Greeks to make war on the Persian Empire. Eleven years later he had defeated the Persian king Darius III three times, taken Egypt, burned Persepolis and led his men to the rivers of the Punjab — and then died in Babylon at the age of 32, his empire stretching from Greece to India.
The route follows the campaign through its turning points, with Arrian's Anabasis, written four centuries later from earlier accounts, as the main guide. Several battlefields can only be placed approximately; their pins are marked as such.
