Final answer:
Indentured servants in North America most likely came from Europe. They served for a specific period of time before being granted freedom. However, as demand for labor increased, the use of African slaves became more prevalent.
Step-by-step explanation:
Indentured servants in North America most likely came from Europe. In the English colonies along the Atlantic coast, indentured servants were brought over from Europe, particularly from countries like England, Germany, and Northern Ireland. These indentured servants served a specific period of time, typically three to seven years, before being granted their freedom. However, as the demand for labor increased in the South, the supply of indentured servants was insufficient, leading to the increased use of African slaves.
