Sea explorations were made by many countries centuries ago. These were headed by the European countries long back. The impulses or urges that influenced the explorers are to desire to take hold of other land for territorial expansion.
Another very important thing to consider as well was the trading. One country had to exchange products to another country. Hence, there were need for them to cross the seas.
In the mid-1800s, the country was divided into 3 sections: North, South, and West. The North's economy was dominated by manufacturing and industry. The South's economy was primarily agriculture with a heavy focus on growing cash crops like cotton, tobacco, rice, and indigo. The West's economy was a mixture of manufacturing and agriculture. The different economies would drive wedges between the different sections and result in different societies and values.
