Sultan Abdullah also known as Raja Bongsu was the de facto ruler of Johor during the reign of Sultan Alauddin Riayat Shah III al-Mansur. The Johor Sultanate made contact with the Dutch East India Company when the Dutch made several visits to Johor; Jacob Van Heemsberk in 1602, Jacob Pietersz Van Enkhuijen in 1603 and Admiral Wijb An Wijck Mei in 1604. Sultan Abdullah made a pact with the Dutch to attack the Portuguese in Melaka and retake the city, putting it under Malay rule.
