<em>The resource that became an important issue in Florida in the 1800s due to an increase in settlers was water.</em>
At the beginning of the 1800s, Spanish people offered many benefits to settlers to come to Florida. Abundant land and water were what Spain offered. It needed to be populated to start working in the land and produce goods for the benefit of Spain.
But as time went by, the resource that became an important issue in Florida in the 1800s due to an increase in settlers was water. This means that when Florida's population grew, they demanded more natural resources. Water from the swamps was not for drinking. So people used fresh water for drinking, bathing, and they used water for farming. So they consumed a lot of the vital liquid. That is why the resource that became an important issue in Florida in the 1800s due to an increase in settlers was water.
At the beginning of the 19th century Spain offered generous parcels of land in Las Floridas to attract settlers and they began to flow both from Spain and from the United States. The American settlers began attacking indigenous settlements that took their revenge by making incursions into US territory. The army of the United States began to cross the border with Spanish Florida to persecute the Seminoles.
John Calvin created the modern democracy. For example the US, the people get to vote for who they want for their leader and the person with the majority of the votes wins.
