Answer:
The abolishment of slavery in Britain and the US had a significant influence on the world today.
Explanation:
These two countries being some of the largest world superpowers, had a major influence on slavery being almost entirely abolished from the open face of the world. Sometimes the US or Britain would force other countries into abandoning the practice of slavery and sometimes they would arm the enslaved people so they could do their own freedom fighting. While slavery does occur in some parts of the world it was widely abolished within 100 years of the US and Britain abolishing it.
