Second American Civil War (RSA)
The Second American Civil War (October 19, 2031 – September 3, 2037), often abbreviated as 2ACW, sometimes called the War of Liberal Secession in the Reformed States and also known as the War of Independence or Revolutionary War in Free States, was a civil war in North America between the R.S. (commonly known as "The Union") and the Free States, comprising New California, New England, Willamette, and the Hawaii Republic, who seceded in 2031 and 2032. The main conflicts leading to the war were the United States Term Limits Act, an act passed by Congress that was widely criticized as an authoritarian power grab, and the subsequent Term Limit riots that erupted across the nation.
Years of controversy were finalized with the United States Term Limits Act, which amended the United States Constitution to let a president serve more then two terms. The passage of the act led to the Term Limit riots, eventually climaxing with the Declaration of Independence of New California, which seized military bases and other federal assets within the state. The war began on October 19, 2031, with federal military forces being deployed in Sacramento. The war further polarized the political landscape of the United States, with most conservatives siding with the U.S. and most liberals siding with the Free States; military enlistment reached record numbers. Three more Free States (nine U.S. states) seceded after the war began. Nearly six years of battle ensued.
The war saw a series of pivotal battles and events that defined its trajectory, beginning with the Battle of Sacramento in December 2031, where Californian forces and several unaffiliated militias successfully repelled federal forces. This was followed by the Siege of Boston in mid-2032, a prolonged and bloody confrontation that ended with the withdrawal of Union troops. The assassination of JD Vance in March 2032 further destabilized the Union, leading to the rise of Ron DeSantis, whose administration intensified the war effort. The Battle of Reno in 2034, which saw heavy casualties but resulted in the Union gaining control of Nevada, was widely seen as the foreshadow of a Reformed States victory, but Operation Pacific Shield in 2035, a failed attempt to blockade the Hawaii Republic, was seen as the main turning point that led the Free States to success. The war ended after years of straining resources, leading to the Treaty of Carson City on September 3, 2037, which officially recognized the independence of New California, New England, Willamette, and Hawaii. DeSantis, seen as being forced into signing the treaty, chose not to run in the 2040 presidential election after declining approval numbers.
