Ivan V

Until 1689, Sophia, Peter’s half sister, ruled as regent for Ivan, who was in poor health. Sophia plotted to force Peter from the throne. But forces loyal to Peter rallied behind him. In late 1689, Peter had Sophia imprisoned for plotting against him. Out of affection for his half brother, Peter allowed Ivan to remain as co-ruler until Ivan’s death in 1689, though Ivan exercised little power.
