Final answer:
The Northwest Territory was organized before Andrew Jackson's troops won the Battle of New Orleans.
Step-by-step explanation:
The Northwest Territory was organized first, before Andrew Jackson's troops won the Battle of New Orleans. The Northwest Territory was organized in 1787 through the Northwest Ordinance, which established a system for settling and admitting new states into the Union. On the other hand, the Battle of New Orleans took place in 1815, after the end of the War of 1812.
