In 1767, people protested about the export of grain from the Island. Anonymous threats were made against shipowners and a law was passed the following year to keep corn in Jersey. In August 1769 the States of Jersey repealed this law, claiming that crops in the Island were plentiful. There was suspicion that this was a ploy to raise the price of wheat, which would be beneficial to the rich, many of whom had ‘rentes’ owed to them on properties that were payable in wheat. As major landowners, the Lemprière family stood to profit hugely.

On Thursday 28 September 1769, a Court called the Assize d’Héritage was sitting, hearing cases relating to property disputes. The Lieutenant Bailiff, Charles Lemprière, sat as the Head of the Court. Meanwhile, a group of disgruntled individuals from Trinity, St Martin, St John, St Lawrence and St Saviour marched towards Town where their numbers were swelled by residents of St Helier. The group was met at the door of the Royal Court and was urged to disperse and send its demands in a more respectful manner. However, the crowd forced its way into the Court Room armed with clubs and sticks. Inside, they ordered that their demands be written down in the Court book. Although the King later commanded that the lines be removed from the book , a transcription survives that shows the crowd’s demands.

The demands of the Corn Riots protestors included:

• That the price of wheat be lowered and set at 20 sols per Cabot.

• That foreigners be ejected from the Island.

• That his Majesty’s tithes be reduced to 20 sols per vergée.

• That the value of the liard coin be set to 4 per sol.

• That there should be a limit on the sales tax.

• That seigneurs stop enjoying the practice of champart (the right to every twelfth sheaf of corn or bundle of flax).

• That seigneurs end the right of ‘Jouir des Successions’(the right to enjoy anyone’s estate for a year and a day if they die without heirs).

• That branchage fines could no longer be imposed.

• That Rectors could no longer charge tithes except on apples.

• That charges against Captain Nicholas Fiott be dropped and that he be allowed to return to the Island without an inquiry.

• That the Customs’ House officers be ejected.
