1945 - 2000 M
After Indonesia gained independence, Tatar Sunda underwent a process of administrative formation and territorial reorganization. On 19 August 1945, West Java was designated as one of the early provinces of the Republic of Indonesia through a decision of the Preparatory Committee for Indonesian Independence. This status was later strengthened by Law Number 11 of 1950.
In subsequent developments, Jakarta, which had previously been associated with West Java, experienced an elevation of status. In 1959, Jakarta obtained a more special administrative position, and in 1961 it was designated as the Special Capital Region through Law Number 2 of 1961. This separation demonstrated Jakarta’s importance as the center of national government.
The next administrative transformation occurred in 2000, when Banten officially became a separate province through Law Number 23 of 2000. This regional division was driven by the aspirations of the Bantenese people to accelerate development, manage industrial and port potential, and strengthen public services.
Thus, in the modern administrative structure, Tatar Sunda is represented not only by West Java but also by the Jakarta Special Capital Region and Banten. The formation of these provinces demonstrates that the geohistorical identity of Tatar Sunda has continued to transform in response to the political, economic, and administrative needs of the Republic of Indonesia.
