Answer: The spoils system
The term "spoils system" was used by President Jackson's political opponents, who took a very negative view of his practice of rewarding political supporters with government jobs. The origin of the term, however, came from one of Jackson's supporters.

Jackson's opponents bristled at that thought and continued to speak against what became known as "the spoils system."
