To earn this achievement go to settings in Universe Mode and turn off Automatic Rivalries.
Doing this is simple enough:
- Customize Universe

- Automatic Rivalries - OFF -
From this point go to the calender and fast forward the universe by a few months and this will cause some, if not all, of the rivalries currently in effect to finish.
Then you go to the Rivalries Tap
- Top option for View All
- Any of the blank spots select Create a New Rivalry
- Select the Length of time and type of Rivalry
- Select Participants for the Rivalry
