The rise of new ports was further stimulated by the arrival of Europeans in search of spices and by the Portuguese defeat of Melaka in 1511 which saw the flight of Muslim trade to other centres.
•Pattani, on the east coast of the Malay peninsula, was a strategic meeting point for Malay and Chinese vessels
•The loosening of ties between overlord and vassal was equally apparent on Java's north coast, where a number of harbourswere well placed to benefit from participation in the spice trade and the diversion of Muslims from Melaka.
•Around 1527 that a coalition of these ports, led by Demak, defeated Majapahitand established their own independence
Ayutthaya had been able to take advantage of growing maritime commerce as a result of administrative reorganization under King Trailok(r. 1448-88). A new ministry, the Mahatthai, was established to supervise civil matters and to oversee foreign affairs and trade.
•In the early sixteenth century some Portuguese ranked Ayutthaya with the most powerful continental empires in Asia, and its prosperity was such that later Thai chroniclers regarded this period as a golden age.
•the rise of small but thriving exchange centresgave a new impulse towards the development of larger groupings, especially in the Philippines and eastern Indonesia. In these areas there had previously been little need or incentive to move towards the formation of 'kingdoms', but a more commercialized environment made increasingly obvious the value of some form of economic and political cooperation in order to strengthen links with wider trading networks
The economic climate of the early sixteenth century nurtured the movement towards political consolidation, a movement apparent not only among coastal ports, but among prominent interior centresas well.
•In the Tai-speaking world Ayutthaya may have dominated the Menambasin among LanNa with its important cities of ChiengmaiandChiengrai, while eastwards lay LanSang which included much of modern day Laos and was focused on two muangatLuangPrabangand Vientiane. But throughout Southeast Asia an equally important factor in the centralizing process was the reputation for religious patronage which normally accompanied the rise of a commercial centre.
•The leadership of Demakon Java's north coast, for example, was based not only on its trading prosperity but on its fame as a centrefor Islamic studies and protector of the venerated mosque associated with the first Muslim teachers on Java.
