Cause → Event → Consequence
Spanish military occupation of the Valtelline and suppression of Protestant rights in the region created tension between France, the Grisons, and Spain. The strategic mountain passes of the Valtelline were critical for Spanish communications between Italian territories and the Low Countries, prompting conflict over control.
On 26 April 1621, French courtier François de Bassompierre signed the Treaty of Madrid. The accord restored the Valtelline to the Grisons, permitted Spain to reoccupy Chiavenna, and guaranteed religious amnesty to Protestants in Valtelline, allowing them to practice their faith freely.
Spain agreed to restore Grisons sovereignty over the Valtelline and forgo use of the alpine passes to open an Italian front in its wars in the Low Countries and Germany. The treaty provided a temporary diplomatic resolution, with France and the Swiss Confederation serving as guarantors of its terms.

Valtelline restored to Grisons; Protestant religious freedoms guaranteed; Spain permitted to reoccupy Chiavenna but forswore use of passes for military expansion.
