The centralist vs. federalist political struggles refer to the conflict between two opposing ideologies regarding the distribution of power within a government. Centralists advocate for a strong central authority that governs with a unified set of laws, while federalists support a decentralized system that allows regional governments to retain significant autonomy. This ideological divide played a crucial role in shaping the political landscape of post-independence Mexico and its territories, including California, as leaders sought to define the future governance structure of their newly independent nation.
