Cotton remained a key crop in the Southern economy after emancipation and the end of the Civil War in 1865. Across the South, sharecropping evolved, in which landless black and white farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs themselves. Until mechanical cotton pickers were developed, cotton farmers needed additional labor to hand-pick cotton. Picking cotton was a source of income for families across the South. Rural and small town school systems had split vacations so children could work in the fields during "cotton-picking."
What part of the southern population worked as sharecroppers?
landless

Neither John nor the rebel barons seriously attempted to implement the peace accord. The rebel barons suspected that the proposed baronial council would be unacceptable to John and that he would challenge the legality of the charter; they packed the baronial council with their own hardliners and refused to demobilise their forces or surrender London as agreed. Despite his promises to the contrary, John appealed to Innocent for help, observing that the charter compromised the pope's rights under the 1213 agreement that had appointed him John's feudal lord. Innocent obliged; he declared the charter "not only shameful and demeaning, but illegal and unjust" and excommunicated the rebel barons. The failure of the agreement led rapidly to the First Barons' War.
Who suspected that the proposed baronial council would be unacceptable?
rebel barons

In the spring of 1800, Napoleon and his troops crossed the Swiss Alps into Italy, aiming to surprise the Austrian armies that had reoccupied the peninsula when Napoleon was still in Egypt.[note 5] After a difficult crossing over the Alps, the French army entered the plains of Northern Italy virtually unopposed. While one French army approached from the north, the Austrians were busy with another stationed in Genoa, which was besieged by a substantial force. The fierce resistance of this French army, under Andre Massena, gave the northern striking force precious time to carry out their operations with little interference. After spending several days looking for each other, the two armies finally collided at the Battle of Marengo on June 14. General Melas had a numerical advantage, fielding about 30,000 Austrian soldiers while Napoleon commanded 24,000 French troops. The battle began favorably for the Austrians as their initial attack surprised the French and gradually drove them back. Melas concluded that he'd won the battle and retired to his headquarters around 3 pm, leaving his subordinates in charge of pursuing the French. However, the French lines never broke during their tactical retreat; Napoleon constantly rode out among the troops urging them to stand and fight. Late in the afternoon, a full division under Desaix arrived on the field and dramatically reversed the tide of the battle. A series of artillery barrages and fortunate cavalry charges managed to decimate the Austrian army, which fled chaotically over the Bormida River back to Alessandria, leaving behind 14,000 casualties. The following day, the Austrian army agreed to abandon Northern Italy once more with the Convention of Alessandria, which granted them safe passage to friendly soil in exchange for their fortresses throughout the region.
