The Battle of Warsaw ends with a Swedish-Brandenburger victory over a larger Polish-Lithuanian force.

The Battle of Warsaw ended on July 30, 1656, with Swedish and Brandenburg forces defeating a larger Polish–Lithuanian army in the Second Northern War.
Fought on July 30, 1656, the Battle of Warsaw was a decisive engagement in the Second Northern War. A combined Swedish-Brandenburger army under King Charles X Gustav confronted Polish–Lithuanian forces led by King John II Casimir. Despite being outnumbered, the more disciplined Swedish and Brandenburg units executed a flanking maneuver that broke the Commonwealth lines. Heavy casualties forced the Polish–Lithuanian army to withdraw across the Vistula River. The victory solidified Swedish control over parts of the Polish–Lithuanian Commonwealth and strengthened Brandenburg’s position in European politics. However, logistical challenges prevented Charles X Gustav from capitalizing further. The battle remains one of the largest military engagements of the 17th century.

Nathaniel Bacon issues the "Declaration of the People of Virginia", beginning Bacon's Rebellion against the rule of Governor William Berkeley.

In 1676, Nathaniel Bacon issued the 'Declaration of the People of Virginia', igniting Bacon's Rebellion against Governor William Berkeley's administration.
Nathaniel Bacon’s Declaration, proclaimed on July 30, 1676, challenged the authority of Virginia’s Governor William Berkeley and colonial elites. Frustrated by frontier attacks, high taxes, and perceived favoritism toward established planters, Bacon rallied small farmers, servants, and freedmen. His manifesto accused Berkeley of corruption and failure to protect settlers from Indigenous raids. Bacon’s forces marched on Jamestown, burning the settlement and seizing political power. The insurrection highlighted deep social and economic divisions in early colonial society. Although Bacon’s sudden death and royal intervention quelled the rebellion, it exposed vulnerabilities in colonial governance. Historians view Bacon’s Rebellion as a precursor to later American revolutionary sentiment and an early test of colonial self-rule.
