A Level One Emergency Alert represented a dire broadcast that the Interstellar Travel Council, a body of the Galactic Republic's, would initiate. This alert signified that a planet presented an exceptionally critical danger to the galaxy. For instance, during the era of the Cold War with the Sith Empire, the Council had no choice but to declare such an alert. This was because the planet Tatooine was identified as the source of a rakghoul epidemic, which subsequently extended its reach across numerous systems belonging to the Republic, the Empire, and those considered neutral.
