Answer:
The first phase of European colonisation of Southeast Asia took place throughout the 16th and 17th centuries. They wanted to gain monopoly over the spice trade as this trade was very valuable to the Europeans due to high demand for various spices suc as pepper, cinnamon,nutmeg and cloves, the arrival of Portuguese, Spanish, Dutch and later French and British marine spice traders. Fiercely competitive, the Europeans soon sought to eliminate each other by forcibly taking control of the production centres, trade hubs and vital strategic locations, beginning with the Portuguese acquisition of Malacca in 1511. Throughout the 17th and 18th centuries, conquests focused on ports along the maritime routes, that provided a secure passage of maritime trade. It also allowed foreign rulers to levy taxes and control prices of the highly desired Southeast Asian commodities.[1] By the 19th century, virtually all Southeast Asian lands had been forced into the various spheres of influence of European global players. Siam, which had served as a convenient buffer state, sandwiched between British Burma and French Indochina was the only country to avoid direct foreign rule. However, its kings had to contend with repeated humiliations, accept unequal treaties among massive British and French political interference and territorial losses after the Franco-Siamese War in 1893 and the Anglo-Siamese Treaty of 1909.[2][3][4]
