The event that occurred first among the options listed is the Brown v. Board of Education ruling, which was decided by the U.S. Supreme Court on May 17, 1954. Here is the chronological order of the events:

1. Brown v. Board of Education ruling (May 17, 1954)
2. Montgomery Bus Boycott (began on December 5, 1955)
3. The federal troops guarding the Little Rock Nine (September 1957)
