Question: The first general strike in the United States was largely organized by the largest and one of the most important 1880's what?

<P0-S0> The Portuguese legislative election of 1983 took place on 25 April. <P0-S1>  The last election, in October 1980 had been won by a right-wing coalition, the Democratic Alliance and Francisco Sá Carneiro had retained office as Prime Minister with an increased majority. <P0-S2>  However, Sá Carneiro, along with other important members of the coalition, died in an aircrash only two months after the election, on 5 December 1980. <P0-S3>  Such happenings caused a massive political instability and Francisco Pinto Balsemão, a senior official of the Social Democratic Party, the largest party in the Alliance, became Prime Minister. <P0-S4>  But Balsemão lacked support from such senior members of his party as Aníbal Cavaco Silva, and several ministers resigned. <P0-S5>  Moreover, the right-wing policy was criticized by the left-wing and by the trade unions, and in February, the General Confederation of the Portuguese Workers, with the support of the Communists, called for a general strike that shook the government. <P0-S6>  The wave of resignations among Balsemão's ministers continued and by the end of the year, he also resigned. <P0-S7>  Because no one inside the Social Democratic Party accepted the office of Prime Minister, the President Ramalho Eanes dissolved the Parliament and called an election for April. <SEP> <P1-S0> The Seattle General Strike Project is a multimedia initiative to chronicle the Seattle General Strike, the first general strike in the United States. <P1-S1>  In February 1919, what began as a wage dispute in the city’s shipyard expanded into a week-long walkout involving more than 50,000 workers that heralded a wave of post-war labor unrest and America’s first red scare. <P1-S2>  The website maintained by the project is one of the foremost collections of primary and academic material on the event, and is part of the Pacific Northwest Labor and Civil Rights History Projects program at the University of Washington. <SEP> <P2-S0>  The general strike was largely organized by the Knights of Labor and the Marxist-leaning Workingmen's Party, the main radical political party of the era. <P2-S1>  When the railroad strike reached East St. Louis, Illinois in July 1877, the St. Louis Workingman's Party led a group of approximately 500 people across the river in an act of solidarity with the nearly 1,000 workers on strike. <P2-S2>  The party transformed, through speeches and organization, an initial strike among railroad workers into a strike by thousands of workers in several industries for the eight-hour day and a ban on child labor. <P2-S3> Generally accepted as the first general strike in the United States, the 1877 St. Louis general strike grew out of the Great Railroad Strike of 1877. <P2-S4>  One speaker was noted to say, At another large rally a black man spoke for those who worked on the steamboats and levees. <P2-S5>  He asked, "Will you stand to us regardless of color?" <P2-S6>  The crowd shouted back, "We will!" <SEP> <P3-S0> Knights of Labor (K of L), officially Noble and Holy Order of the Knights of Labor, was the largest and one of the most important American labor organizations of the 1880s. <P3-S1>  Its most important leader was Terence V. Powderly. <P3-S2>  The Knights promoted the social and cultural uplift of the workingman, rejected socialism and anarchism, demanded the eight-hour day, and promoted the producers ethic of republicanism. <P3-S3>  In some cases it acted as a labor union, negotiating with employers, but it was never well organized, and after a rapid expansion in the mid-1880s, it suddenly lost its new members and became a small operation again.
