The Rump Parliament, which revived after the army's intervention, clashed with military leaders by asserting control over officer appointments, angering the army and jeopardizing its support.
2. Tensions between the army and parliament intensified, especially after Sir George Booth's Royalist uprising was crushed, and the Rump failed to address the country's financial and political crises.
3. The Rump's decision to dismiss senior army leaders like Lambert and Desborough led to open rebellion from the army, culminating in the army's march to Westminster on 13 October to end the Rump's authority.
