Why is 1807 significant

A. The sultan of the Ottoman Empire issued a similar law restricting the slave trade

B. British parliament outlawed slavery in Britain and it all of its colonies

C. The government of Egypt signed an agreement with Britain restricting the slave trade

D. The British parliament responded to the popular outcry and abolished the slave trade. This did not end slavery

The correct answers is option B.

B. British parliament outlawed slavery in Britain and it all of its colonies.

It is significant because in that year the members of the Society for the Abolition of the Slave Trade decided to concentrate on a campaign to persuade Parliament to prohibit the trading in slaves, for tactical reasons.

It was not until 1807, when the evils of the trade were generally accepted, that the law was able to pass both Houses.
