The rise of the middle class, or bourgeoisie, significantly contributed to multiple historical events, but one of the most direct results was the Industrial Revolution.
The Industrial Revolution, which began in the late 18th century, was primarily driven by the burgeoning middle class that benefitted from increased commerce and manufacturing. This new economic class demanded goods and services, leading to the establishment of factories and urban centers. While migration from rural areas to urban centers, as well as the American and French Revolutions, were influenced by the rise of the middle class, the Industrial Revolution stands out as a direct consequence of its economic and social emergence.
Therefore, the correct answer reflecting the event that occurred as a result of the rise of the middle class is the Industrial Revolution.
