Second Spanish Civil War (Mercbl)

The Second Spanish Civil War was a military conflict between the allied forces of the Basque United Front (BUF) and the Catalan Socialist Front for Unity(CSFU) against the Kingdom of Spain. It ended when the military forces of the Kingdom of Spain overthrew the government to form the Union of Iberian Provinces (UIP).

Before 2030
In the years preceding the war tensions had long been rising between various groups in Spain. The Parliament of Catalonia had already declared independence on the 27 of October 2017 but without international recognition it went nowhere, following this, tensions continued to rise until 1 June 2025 when two assassins failed to kill King Felipe VI of Spain. The assassination attempt and ensuing Spanish crackdown on insurgents in Catalonia lead to a power struggle that toppled the Parliament of Catalonia and lead to the establishment of the Catalan Socialist Front for Unity under the leadership of Miguel Batanero. Following this change Miguel established an alliance the Basque United Front, another Spanish independence movement. Miguel sought to peacefully establish independence, but also beefed up the forces of the CSFU in case of Spanish attack.

However Miguel Batanero died from a heart attack on 29 November 2029 and was replaced by the 25 year old Lidia Gueldos. Immediately the new leader looked to more drastic options and on the 2 of January 2030 a bomb went off outside the Bank of Spain killing over 50 people, the perpetrators were discovered to be CSFU agents and on the 9 of January 2030, The CSFU declared war on Spain.

2030
Following the outbreak of war, a large Spanish army force was trapped in Barcelona, following several days of conflict around the city both the I brigade and VI brigade who had been stationed in Barcelona to quell the growing unrest surrendered to the Catalan forces. This would be very important in the early stages of the war as equipment taken from the surrounded forces would allow the Catalan forces to resist the Spanish advance until more support came from outside parties. By the end of January, most of the area of Catalonia had been occupied and the rebel forces began to establish a defensive line to protect against the eventual Spanish counterattack. Meanwhile unrest was also brewing in the Basque Region, leading to a second rebel group, spurred on by the Catalonians declaring independence for the Basque Federal Republic in the Pyrenees, with it’s capital in the town of Canfranc.

As tensions had been rising between Spain and the Mediterranian Security Accord, the latter wasted no time supporting the rebellious Catalonians, shipments of infantry equipment, artillery and ammunition began in May.
