How secure was the empire in 1707?

In 1707, the security of the British Empire was relatively strong, bolstered by its naval supremacy and expanding colonial holdings. However, it faced challenges such as internal dissent, notably in Scotland with the Jacobite risings, and external threats from rival powers like France and Spain. The Act of Union in 1707, which unified England and Scotland, aimed to stabilize the empire but also introduced new tensions. Overall, while the empire was robust, it was not without significant vulnerabilities.
