Why parliament needed money to fight the Scots?

Parliament needed money to fight the Scots due to the financial strain of military campaigns and the ongoing conflict with Scotland, particularly during the Wars of the Three Kingdoms. The costs of raising and maintaining an army, along with the expenses of warfare, necessitated seeking funds from Parliament. Additionally, the political and social tensions of the time, including the need to assert control over Scotland and manage internal dissent, heightened the demand for financial resources. This led to increased reliance on Parliament for funding, particularly during periods of conflict.
