How did Malaysia gather more than 13000 islands into one country?

First, relying on federalism, each region has independent administrative power, but it is also subject to the state. Indonesia has a very long history, but it has also made many attempts to establish state power. At the beginning, Indonesia had a large number of colonies and was not completely unified into a country. But later, as the world began to move towards unity, various places declared independence one after another. In this process, Indonesia seized the opportunity to form a capitalist state power. This political system has successfully gained a foothold in Malaysia under the long-term historical test. So Indonesia adopted the western federalism. In addition, the United States supports Indonesian soldiers to overthrow the former regime and establish a new country. With the help of the United States, Indonesia's capitalist system has developed for a long time. Therefore, federalism provides a favorable unified system for decentralized Indonesia.

Second, Indonesia was unified because of the early Dutch.

Thanks to the efforts of the Dutch, Indonesia has been able to unify more than 3,000 islands into one country. In the initial exploration around the world, many areas were isolated from the world. The Dutch first established a unified country in Indonesia. And through constant fighting with other countries. After conquering the tribal cultures all over Indonesia, the Netherlands officially managed Indonesia as a country. With the efforts of the early Dutch, scattered Indonesia was closed into a country with a unified cultural system.

Third, Indonesia became a country thanks to the development of immigrant culture.

At the beginning, Malaysia and Indonesia were scattered, and no people from other countries moved to these places, so the culture was closed to a certain extent. With the integration and exchange of global cultures, more and more immigrants are pouring into Indonesia and Malaysia. These countries have become more mature in the choice of national political system and can accommodate more cultures, which has created a unified culture and system, although they are now scattered islands.
