The Ottoman expedition to Aceh started from around 1565 when the Ottoman Empire endeavoured to support the Aceh Sultanate in its fight against the Portuguese Empire in Malacca.[1][2] The expedition followed an envoy sent by the Acehnese Sultan Alauddin Riayat Syah al-Kahhar (1539–71) to Suleiman the Magnificent in 1564, and possibly as early as 1562,[3] requesting Ottoman support against the Portuguese.[4]
