Business career

Defoe entered the world of business as a general merchant, dealing at different times in hosiery, general woollen goods, and wine. His ambitions were great and he was able to buy a country estate and a ship (as well as civets to make perfume), though he was rarely out of debt. On 1 January 1684, Defoe married Mary Tuffley at St Botolph's Aldgate. She was the daughter of a London merchant, and brought with her a dowry of £3,700—a huge amount by the standards of the day. Given his debts and political difficulties, the marriage may have been troubled, but it lasted 47 years and produced eight children.

In 1685, Defoe joined the ill-fated Monmouth Rebellion but gained a pardon, by which he escaped the Bloody Assizes of Judge George Jeffreys. Queen Mary and her husband William III were jointly crowned in 1689, and Defoe became one of William's close allies and a secret agent. Some of the new policies led to conflict with France, thus damaging prosperous trade relationships for Defoe. In 1692, he was arrested for debts of £700 and, in the face of total debts that may have amounted to £17,000, was forced to declare bankruptcy. He died with little wealth and evidently embroiled in lawsuits with the royal treasury.

Following his release from debtors' prison, he probably travelled in Europe and Scotland, and it may have been at this time that he traded wine to Cadiz, Porto and Lisbon. By 1695, he was back in England, now formally using the name "Defoe" and serving as a "commissioner of the glass duty", responsible for collecting taxes on bottles. In 1696, he ran a tile and brick factory in what is now Tilbury in Essex and lived in the parish of Chadwell St Mary nearby.
