Which of these civilizations traded with India during the 1400s?

A: United states
B: Swahili Coast
C: Axum Empire
D: Britain

During the 1400s, the civilizations that traded with India were:

B: Swahili Coast
C: Axum Empire
D: Britain

C: Axum Empire

Though it is worth noting that the Axum Empire was declining in the 1400s and its trading activity with India had already decreased significantly by that time.

To determine which of these civilizations traded with India during the 1400s, we can analyze historical records and examine the geographical and historical context. Here is an explanation for each option:

A: United States - The United States did not exist as a country in the 1400s, so it is unlikely they traded with India during that time period.

B: Swahili Coast - The Swahili Coast refers to a region along the eastern coast of Africa that was known for its trading activities during ancient and medieval times. The Swahili Coast had extensive trade connections with various regions, including India. Therefore, it is plausible that the Swahili Coast civilization traded with India during the 1400s.

C: Axum Empire - The Axum Empire, located in present-day Ethiopia and Eritrea, was an ancient kingdom that flourished from the 1st century CE to the 7th century CE. While the civilization of Axum had trade relations with various regions, including the Roman Empire, it is less likely that they traded directly with India during the 1400s specifically.

D: Britain - During the 1400s, Britain was not involved in direct trade with India. It was not until the 17th century that the British established significant trading relationships with India through the establishment of the British East India Company.

Based on the explanations provided above, the most likely civilization to have traded with India during the 1400s is the B: Swahili Coast.
