May Day in the context of "Village green"

Midsummer or Midsommar (Swedish: [ˈmɪ̌ˌsɔmːar] or [ˈmǐːdˌsɔmːar]) is a celebration of the season of summer, taking place on or near the date of the summer solstice in the Northern Hemisphere, the longest day of the year. The name "midsummer" mainly refers to summer solstice festivals of European origin. These cultures traditionally regard it as the middle of summer, with the season beginning on May Day. Although the summer solstice falls on 20, 21 or 22 June in the Northern Hemisphere, it was traditionally reckoned to fall on 23–24 June in much of Europe. These dates were Christianized as Saint John's Eve and Saint John's Day. It is usually celebrated with outdoor gatherings that include bonfires, maypole dancing and feasting.

Hyde Park is a 350-acre (140-hectare), historic Grade I-listed urban park in Westminster, Greater London. A Royal Park, it is the largest of the parks and green spaces that form a chain from Kensington Palace through Kensington Gardens and Hyde Park, via Hyde Park Corner and Green Park, past Buckingham Palace to St James's Park. Hyde Park is divided by the Serpentine and the Long Water lakes.

The park was established by Henry VIII in 1536 when he took the land from Westminster Abbey and used it as a hunting ground. It opened to the public in 1637 and quickly became popular, particularly for May Day parades. Major improvements occurred in the early 18th century under the direction of Queen Caroline. The park also became a place for duels during this time, often involving members of the nobility. In the 19th century, the Great Exhibition of 1851 was held in the park, for which The Crystal Palace, designed by Joseph Paxton, was erected.

Saint John's Eve, starting at sunset on 23 June, is the eve of the feast day of Saint John the Baptist. It is one of only two feast days marking a saint's earthly birth (the other being the nativity of the Blessed Virgin Mary on 8 September); all other saint’s days mark their deaths (dies natalis, their “birth” into Heaven), or some other important event. The Gospel of Luke (Luke 1:26–37, 56–57) states that John was born six months before Jesus; thus, the feast of John the Baptist’s birth was fixed on 24 June, six months before Christmas. In the Roman calendar, 24 June was the date of the summer solstice, and Saint John's Eve is closely associated with Midsummer festivities in Europe. Traditions are similar to those of May Day, and include bonfires (Saint John's fires), feasting, processions, church services, and gathering wild plants.

A maypole is a tall wooden pole erected as a part of various European folk festivals, around which a maypole dance often takes place.

The festivals may occur on 1 May or Pentecost (Whitsun), although in some countries it is instead erected during Midsummer (20–26 June). In some cases, the maypole is a permanent feature that is only utilized during the festival, although in other cases it is erected specifically for the purpose before being taken down again.

Blutmai (English: Bloody May, lit. 'Blood May') was an outbreak of political violence that occurred in Berlin from 1 to 3 May 1929.

It occurred when the Communist Party of Germany (KPD) held May Day marches in defiance of a ban on public gatherings in Berlin ordered by the city's police chief Karl Zörgiebel of the Social Democratic Party (SPD). The Berlin Police responded with an immediate and harsh crackdown. Often without regard to whether the persons involved were demonstrators or bystanders, they forcibly and sometimes violently dispersed the crowds that formed. As the day progressed, street battles developed between the protestors and the police, who used firearms and armoured cars. The violence lasted until the afternoon of 3 May, mostly in the working-class neighbourhoods of Wedding and Neukölln.

International Workers' Day, also called Labour Day in some countries and often referred to as May Day, is a celebration of labourers and the working classes that is promoted by the international labour movement and occurs every year on 1 May, or the first Monday in May.

Traditionally, 1 May is the date of the European spring festival of May Day. The International Workers Congress held in Paris in 1889 established the Second International for labor, socialist, and Marxist parties. It adopted a resolution for a "great international demonstration" in support of working-class demands for the eight-hour day. The date was chosen by the American Federation of Labor to commemorate a general strike in the United States, which had begun on 1 May 1886 and culminated in the Haymarket affair on 4 May. The demonstration subsequently became a yearly event. The 1904 Sixth Conference of the Second International, called on "all Social Democratic Party organisations and trade unions of all countries to demonstrate energetically on the First of May for the legal establishment of the eight-hour day, for the class demands of the proletariat, and for universal peace".
