John spent much of 1205 securing England against a potential French invasion. As an emergency measure, John recreated a version of Henry II's Assize of Arms of 1181, with each shire creating a structure to mobilise local levies. When the threat of invasion faded, John formed a large military force in England intended for Poitou, and a large fleet with soldiers under his own command intended for Normandy. To achieve this, John reformed the English feudal contribution to his campaigns, creating a more flexible system under which only one knight in ten would actually be mobilised, but would be financially supported by the other nine; knights would serve for an indefinite period. John built up a strong team of engineers for siege warfare and a substantial force of professional crossbowmen. The king was supported by a team of leading barons with military expertise, including William Longespee, William the Marshal, Roger de Lacy and, until he fell from favour, the marcher lord William de Braose.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many knights out of ten would be mobilised?

Pagan's collapse was followed by 250 years of political fragmentation that lasted well into the 16th century. Like the Burmans four centuries earlier, Shan migrants who arrived with the Mongol invasions stayed behind. Several competing Shan States came to dominate the entire northwestern to eastern arc surrounding the Irrawaddy valley. The valley too was beset with petty states until the late 14th century when two sizeable powers, Ava Kingdom and Hanthawaddy Kingdom, emerged. In the west, a politically fragmented Arakan was under competing influences of its stronger neighbours until the Kingdom of Mrauk U unified the Arakan coastline for the first time in 1437.
