It is because of a political compromise
reached after a civil conflict in the late 19th century.
Originally, Sucre was Bolivia's sole capital and the center
of political power.
However, as the country's economy shifted from the silver
mines around Sucre to the booming tin industry centered near La Paz, La Paz
became more economically and politically influential.
So now, Sucre is the constitutional and official
capital, where the Supreme Court is located.
La Paz is the seat of government (administrative capital), where the executive and legislative branches operate.
