Final answer:
The Labour Party, established in 1900, was the major British political party founded as a result of the profound social changes brought about by the Industrial Revolution.
Step-by-step explanation:
The major British political party founded during the Industrial Revolution was the Labour Party. Throughout the 19th century, Britain's two dominant parties were the Whig Party, which later evolved into the Liberal Party, and the Tory Party, which became the modern Conservative Party. Queen Victoria witnessed significant changes in the political landscape, including the push for political reforms. The Labour Party, however, has its roots at the end of this era, specifically formed in 1900 to represent the interests of the urban working class that had grown substantially as a consequence of the Industrial Revolution.
