Under the Oaks is a historical site honoring the birthplace of the Republican Party. On July 6, 1854, a state convention of anti-slavery men was held in Jackson, Michigan, to found a new political party. Since the convention day was hot and the huge crowd could not be accommodated in the hall, the meeting adjourned to an oak grove on "Morgan's Forty" on the outskirts of the town known today as "Under the Oaks". Today, this park includes a plaque to commemorate the event and benches for resting under the oak trees.
