In 1648, Abdul Jalil III attacked Pahang in an attempt to reassert his position as Ruler of Johor-Pahang. Aceh eventually abandoned its claim over Pahang in 1641 - the same year Portuguese Malacca fell to the Dutch. With the decline of Aceh, Johor-Pahang gradually extended its suzerainty over Riau-Lingga islands, creating the Johor-Riau-Lingga Empire.[51]
