On June 28, the following notable historical events related to Missouri have been recorded:

• 1839: The Mormon War in Missouri, which involved conflicts between Mormon settlers and local militias, had largely concluded by this time, but on or around June 28, 1839, Mormon refugees were still fleeing Missouri after Governor Lilburn Boggs’ expulsion order of 1838. This marked a significant moment in Missouri’s religious and social history.
• 1862: During the Civil War, Confederate guerrilla activity persisted in Missouri. While no specific battle is tied to June 28, this date falls within a period of raids and skirmishes, particularly in rural areas like Johnson County, as bushwhackers disrupted Union control.
• 1928: The Bagnell Dam project, which later created the Lake of the Ozarks, was approved by federal authorities on or around June 28. Construction began soon after, transforming Missouri’s economy and tourism in the region.
