Following their exile to Savoy, Queen Amalia Ludovica and the Royalist court engaged in a desperate diplomatic campaign to secure foreign intervention against the new French Republic. Their pleas were rejected by the major European powers, including Austria, Prussia, and Russia, who feared that intervening would spark similar insurrections within their own borders. Faced with total isolation and the indifference of her fellow Christian monarchs, the Queen made the shocking decision to solicit military aid from the Islamic Sultanate of Madjrit. Despite the horror of her court, the alliance was sealed, inviting a traditional enemy of Christendom to invade French soil in a bid to restore the Bourbon throne.

In Paris, the Republicans worked to dismantle the symbols of the Ancien Régime while holding King Henri V as a prisoner in the Tuileries Palace. Rebranded as the "Citizen Sovereign," the King was reduced to a political puppet, forced to publicly endorse revolutionary decrees to lend legitimacy to the new government. Behind the scenes, Henri sank into a deep depression, managing to smuggle a letter to his brother that revealed his true suffering and his belief that the revolution would eventually claim his life. Meanwhile, the People's Assembly fractured into competing factions: the militaristic Sentinels, the radical People’s Vanguard, and the moderate Forum. The Sentinels ultimately prevailed, passing legislation to form a "Revolutionary Army" through national conscription to crush the noble resistance in the countryside.

The Republic’s first major military offensive ended in catastrophe at the Battle of Jonquieres in June 1792. The newly formed Army of the Interior, led by the politically appointed General Jean Aubry, attempted to overwhelm a smaller force of nobles and mercenaries. Despite their numerical superiority, the inexperienced Republican conscripts were systematically dismantled by the professional discipline and cavalry tactics of the aristocratic army. The defeat resulted in 12,000 Republican casualties and exposed the hollowness of the revolutionary military, shattering confidence in the Sentinels' leadership. Capitalizing on this weakness, the Sultanate of Madjrit launched its invasion across the Pyrenees in September, plunging France into a two-front war against internal Royalists and a foreign empire.
