The correct answer to this open question is the following.
There is no question here. Just a statement. If this is a true or false question, then the answer is "true."
It is true that the Proclamation of 1763, it drew a line along the crest of the Appalachian Mountain Range, and declared that no white settlement could take place west of that line. It was significant because it drew a "color line" in North America and admitted Indigenous Peoples had sovereignty.
After the English victory over the French in the French and Indian War, George III, the King of England, issued the Proclamation of 1763. It established an imaginary line that divided the East coast American colonists settlings from the western Indian territories. The idea was that white colonists respected the Native American Indian tribe's territories and forbid the invasion of their lands.
The phrase which explains what was significant about the Declaration of Independence was that it set up a government system without any leaders. This was sort of a system of emancipation from the British government for the thirteen colonies and this document essentially made the United States free from the rule of the British monarchy.
