The Tea Act of 1773 angered colonists because it favored a British company over Colonial merchants.
Explanation:
The Tea Act was a law promulgated by the British Parliament in May 1773 that allowed the British East India Company to sell its tea in the Thirteen Colonies of North America without paying taxes.
The law was enacted to try to relaunch the Company, which was in a serious crisis, giving it a monopolistic place in British commerce.
As a result, a boycott of British tea by the settlers of the Thirteen Colonies was initiated, culminating in the Boston Tea Party.
It was a mixture of various reasons, although for the Spanish and Portuguese it was a question of reaching India for spice trades after the embargo instated on them by the Ottoman Turks.
The Portuguese went around Africa, and the Spanish tried sailing west across the barren ocean, and accidentally discovered America through Columbus.
