The Christian kingdoms of Denmark and Sweden were also greedy for conquests on the Eastern shores of the Baltic. While the Swedes made only one failed foray into western Estonia in 1220, the Danish Fleet headed by King Valdemar II of Denmark had landed at the Estonian town of Lindanisse (present-day Tallinn) in 1219. After the Battle of Lindanise the Danes established a fortress, which was besieged by Estonians in 1220 and 1223, but held out. Eventually, the whole of northern Estonia came under Danish control.
