The Conquest of Santarém took place on 15 March 1147, when the troops of the Kingdom of Portugal under the leadership of Afonso I of Portugal captured the Almoravid city of Santarém.


On 10 March 1147, King Afonso I of Portugal departed from Coimbra with 250 of his best knights[2] intending to capture the Moorish city of Santarém, a goal that he had previously failed to achieve.[2] The conquest of Santarém was of vital importance to Afonso's strategy; its possession would mean the end of the frequent Moorish attacks on Leiria and would also allow a future attack on Lisbon.[citation needed]

The plan now was to attack the city during the night under cover of darkness, in order to catch the Moorish garrison by surprise.[2] King Afonso had previously sent the Portuguese Mem Ramires to Santarém disguised as a businessman, in order to secretly study the city for the conquest.[2]

After the first day of the journey from Coimbra to Santarém, King Afonso I sent an emissary to Santarém announcing to the Moors that the truce had ended, for which three days' notice was required.[1]
