Constância (pronounced as /pt/) is a municipality in Santarém District in Portugal. The population in 2011 was 4,056,[1] in an area of 80.37 km².[2]
Conquered from the Moors in 1150, it was given the status of 'town' in 1571 through a charter from King Sebastian. Portuguese national poet Luís de Camões lived in exile there between 1548 and 1550. In 1809, the English army met in Constância before marching on Spain, on their way to the Battle of Talavera, where Wellington defeated the French.
