Republic of Venezuela (modern, separate state)
Who & why: regional resistance to rule from distant Bogotá, led by General José Antonio Páez, pulls Venezuela out of Gran Colombia in 1830, the same year Bolívar dies; it re-forms as its own separate republic. Venezuela cycles through 19th-century caudillo rule and instability, a long 20th-century oil boom that made it briefly one of Latin America's wealthiest states, and since 1999 Hugo Chávez's "Bolivarian Revolution" and its successor government under Nicolás Maduro, alongside a severe economic and migration crisis in the 2010s–20s.
What it represents: the same yellow-blue-red tricolor inherited from Gran Colombia, with a star added for each founding province — seven originally, rising to eight in 2006 under Chávez to mark the historic province of Guayana — arranged in an arc.
