Portugal emerged as a country in 1143, after a 15 year rebellion by Dom AfonsoHenriques (Afonso I). AfonsoHenriques defeated his mother Countess Teresa of Portugal, regent of the County (Condado) of Portugal and loyal to the Kingdom of Leon, at the battle of Sao Mamede (Batalha de Sao Mamede) near the town of Guimaraes, in June of 1128.  Countess Teresa was imprisoned and exiled by her son, and died in 1130. Guimaraes is therefore known as the birthplace city of Portugal.
