Europeans first became interested in Africa for trade route purposes. They were looking for ways to avoid the taxes of the Arab and Ottoman empires in Southwest Asia. Sailing around Africa was the obvious choice, but it was a long voyage and could not be completed without “pit stops” along the way.

Tyler's opponents regularly called him "His Accidency" and addressed correspondences to him as "Vice President" or "Acting President" (letters which he returned unopened).
When his term ended in 1845, he did not seek election.
