In 1833, Owen returned from the
United States, and declared the need for a
guild-based system of co-operative production. He was able to gain the support of the Builders' Union, which called for a Grand National Guild to take over the entire building trade. The new body, unlike other organisations founded by Owen, was open only to
trade unionists and, as a result, initially Owen did not join it. Its foundation coincided with a period of industrial unrest, and strikes broke out in
Derby,
Leeds and
Oldham. These were discouraged by the new union, which unsuccessfully tried to persuade workers to adopt co-operative solutions. Six labourers in
Tolpuddle,
Dorset attempted to found a
friendly society and to seek to affiliate with the Grand National. This was discovered, and in 1834 they were convicted of swearing unlawful oaths, and they were sentenced to
transportation for seven years. They became known as the
Tolpuddle Martyrs and there was a large and successful campaign led by activist
William Lovett to reduce their sentence. They were issued with a free pardon in March 1836. == Dissolvement ==
