The First Battle of Custoza was fought on July 24 and 25, 1848, during the First Italian War of Independence between the armies of the Austrian Empire, commanded by Field Marshal Radetzky, and the Kingdom of Sardinia, led by King Charles Albert of Sardinia-Piedmont.

Democrats of the Palatinate and across Germany considered the Baden-Palatinate insurrection to be part of the wider all-German struggle for constitutional rights. Franz Sigel, a second lieutenant in the Baden army, a democrat, and a supporter of the provisional government, developed a plan to protect the reform movement in Karlsruhe and the Palatinate.

The Young Irelander Rebellion was a failed Irish nationalist uprising led by the Young Ireland movement, part of the wider Revolutions of 1848 that affected most of Europe. It took place on 29 July 1848 at Farranrory, a small settlement about 4.3 km north-northeast of the village of Ballingarry, South Tipperary.

In response, the Young Ireland Party launched its rebellion in July 1848, gathering landlords and tenants to its cause.
