Why did the indigneous population of central America decline with the arrival of europeans?

The indigenous population of Central America declined significantly following the arrival of Europeans due to a combination of factors, including violent conquest, enslavement, and the introduction of diseases such as smallpox, for which the indigenous people had no immunity. European colonizers often engaged in brutal military campaigns to subjugate native populations, leading to widespread death and displacement. Additionally, the disruption of traditional lifestyles and economies further weakened indigenous communities, contributing to their decline.
