The Ayutthaya invasions of the Malacca Sultanate were conflicts that occurred in 15th century when the Ayutthaya Kingdom under King Borommatrailokkanat attempted to invade the Malacca Sultanate.
The Ayutthaya invaded Malacca twice during the conflict: once around 1447 and once in 1456. Both invasions were repelled by Malacca.
The Malacca Sultanate established a tributary relationship with the Ming dynasty soon after its foundation at the turn of the 15th century. When Ayutthaya's growing power began to threaten Malacca, the Ming warned Ayutthaya that Malacca was a Ming vassal and shouldn't be interfered with. By the time that its Ming protectors adopted an isolationist foreign policy in the mid-15th century, Malacca had won enough time to build up its own strength. When Muzaffar Shah became sultan in 1445 or 1446, he ended the tributary payments that the Sultanate had previously made to Ayutthaya.
Ayutthaya began its first attack around 1447, which was ultimately thwarted by Malaccan forces led by Tun Perak.
The occurred in 1456 after the first failed attempt to invade Malacca, and Ayutthayan forces were again defeated by Tun Perak's Malaccans. Following their defeat, some Ayutthayan commanders surrendered in Batu Pahat and were later sent to Singapore.
After repelling the Ayutthayan invasions, Malacca seized control over the southern part of the Malay Peninsula.
Muzaffar Shah ruled the Malacca Sultanate until his death in 1459, when his son, Mansur Shah, became sultan at the age of 27. Raja Abdullah invaded the Old Pahang Kingdom, ruled by Maharaja Dewa Sura, a relative and subject of the king of Ayutthaya. Dewa Sura was eventually taken as a prisoner of war, and Mansur Shah subsequently married his daughter, Wanang Sri. Whenever, the commander, Sri Bija Diraja, has been given to rule Pahang. By which, there are follow intimates of the tales regardless to the king of Pahang and were later expertise to mahout.

According to the History of Ming from the book that it states in 1456, sultan of Malacca Sultanate Muzaffar Shah had sent a tribute to the Ming to be invested as a king, but then again it was later asked if the synchronism between the China and the Siamese chronicles were correct or not, the inferences of Muzaffar Shah, the actions of refrained to even sought recognition to China during the previous decades on the account of which the embroilment with Siamese previously, or lately perhaps of the guilt conscience following of his brother death by murder.
