Why did the Brazilian capital move from Rio de Janeiro to Brasilia?

1. Relieve the pressure of coastal cities. Coastal cities are sparsely populated and lack of resources. Move the capital to ease the pressure in all aspects.

2. (Understandably) In order to develop the inland. Inland areas are vast and sparsely populated, so moving the capital is a powerful means to promote the development of inland areas.

Although many people support moving the capital, many people think that there is a problem in setting the capital in Brasilia. I heard that the decision to move the capital to Brasilia was made through divination.
