Why did Revolutionnary France declare war on Britain and the Netherlands in February 1793 ?

[Thutmosis]

The war between France and Austria started in April 1792.

Supporters of Louis XVI hoped that the Austrian armies would crush the Revolutionnary armies, radicals hoped that fighting a common foe would help to "unite" the country and destroy the princes'armies in Koblenz.

During the summer of 1792, the government in Paris felt threatened by the invasion of the Austrian and Prussian armies.

In August, the Paris commune stormed the Tuilleries palace.

In early September, prisons were assaulted with thousands of people murdered.

On 20 September 1792, the battle of Valmy was won, and the republic proclaimed/monarchy abolished.

In January 1793, Louis XVI was sentenced to death and beheaded. Very shortly after, France declared war on Britain and the Netherlands. Very shortly after, France was also at war with Naples, Russia, and many other countries.

This latter act, arguably, did start a period of conflicts that would engulf Europe and last for 23 years.

But then, why declare war on Britain and the Netherlands ? Were there any threat by any of those states, any active support to Austria, or any political calculation ?

France had previously promised Britain it would not invade the Netherlands if Britain remained neutral. However when Louis XVI was executed the British government was under pressure from the aristocracy to make some response. Britain expelled the French ambassador and France responded by declaring war.
