A more thorough explanation:

Definition: A conqueror is someone who acquires territory by force during war with the intention of exercising sovereignty. It can also refer to the first person who acquired land by purchase, bringing an estate into a family.

Example 1: Alexander the Great was a famous conqueror who conquered many lands and expanded his empire through military conquest.

Example 2: In medieval times, a conqueror could also refer to the first person who purchased land and brought it into their family's possession.

Example 3: In legal petitions, the term "conqueror" was used to introduce a complaint, such as "Conqueror quod...," which means "I complain that...".

These examples illustrate how a conqueror can be someone who gains territory through military force or through legal means such as purchasing land. The legal use of "conqueror" as a way to introduce a complaint shows how the term can also be used in a legal context.
