How did Portuguese Abuque monopolize the eastern maritime trade?

In order to stay in India for a long time, Abukui adopted the most direct and effective method. He encouraged the Portuguese to intermarry with the local people, thus achieving the effect of "colonization". After occupying Malacca (15 1 1) and Hormuz Island (15 15), they finally squeezed out the Arab forces as they wished and monopolized the eastern maritime trade. His successors established many new settlements along the West Bank and Bengal, such as Wu Di, Dammam, Salsat, Bassein, Joel, Mumbai and Hugli. By the middle of16th century, Portugal had taken control of Ceylon.
