The Shakespeare Jubilee was staged in Stratford-upon-Avon between 6–8 September 1769.
 The jubilee was organised by the actor and theatre manager David Garrick to celebrate the Jubilee of the birth of William Shakespeare, although it was in 1616 when he died.
 It had a major impact on the rising tide of bardolatry that led to Shakespeare becoming established as the English national poet.
 Thomas Arne composed the song "Soft Flowing Avon" for the Jubilee.
Nationality is a legal relationship between an individual person and a state.
 Nationality affords the state jurisdiction over the person and affords the person the protection of the state.
 What these rights and duties are vary from state to state.
Avon Water is a small river in the south of England, flowing through the New Forest in Hampshire to the sea.
 It should not be confused with the larger River Avon, which also flows through Hampshire.
Multiple citizenship, also called dual citizenship or multiple nationality or dual nationality, is a person's citizenship status, in which a person is concurrently regarded as a citizen of more than one state under the laws of those states.
 There is no international convention which determines the nationality or citizen status of a person, which is defined exclusively by national laws, which vary and can be inconsistent with each other.
 Multiple citizenship arises because different countries use different, and not necessarily mutually exclusive, criteria for citizenship.
 Colloquial speech refers to people "holding" multiple citizenship but technically each nation makes a claim that this person be considered its national.
Venezuelan nationality law is based on the principle of Jus soli.
 Any person born in Venezuela acquires Venezuelan citizenship at birth, irrespective of nationality or status of parents.
 Nationality law is regulated by Section 1 of Chapter 2 of the Constitution of Venezuela and by the Nationality and Citizenship Act of 2004 .
The area first became known to Europeans in the sixteenth century as the river now known as the Avon appears on maps from this period.
 By 1686 Jean-Baptiste-Louis Franquelin's map of Acadia/Nova Scotia defines the area, showing the local tributaries flowing into the Avon River.
 One of these tributaries, the Cacaquit or modern day Halfway River, which now forms the northern boundary of the community, is indicated on the map.
 By 1680 Acadian farmers had migrated out of the Port Royal area and began settling the eastern end of the Annapolis Valley including the lands about Mount Denson, then known as Pisiquit.
 Census records indicate Etienne Rivet was one of the first settlers to establish a farm.
 He and his progeny farmed the nearby marshlands south of Mitchener's Point as well as those in the Cacaquit River valley.
 His son, Etienne, operated a mill on the Cacaquit near where the river meets the uplands, just beyond the southern boundary of today's town of Hantsport.
 By the 1690s Mount Denson was incorporated into the Acadian parish of Paroisse de Sainte Famille (established in 1698).
 When the Expulsion of the Acadians began in 1755 the area's male residents were detained at Fort Edward and later in the fall deported along with their families from the province.
Soft Flowing Avon was a 1769 song with music written by Thomas Arne and lyrics by David Garrick.
 It was composed for and first staged at the Shakespeare Jubilee in Stratford-upon-Avon in 1769.
 The lyrics refer to the River Avon which flows through the town, the birthplace of William Shakespeare.
 The piece was later part of the Shakespeare Pageant performed at the Drury Lane Theatre.
 The song and the Jubilee were part of the growing culture of Bardolatry which sprung up in the eighteenth century.
The River Avon or Avon is a river in central England.
 Flowing generally southwestwards, it is a major left-bank tributary of the River Severn, of which it is the easternmost tributary system.
 It is also known as the Warwickshire Avon or Shakespeare's Avon, to distinguish it from several other River Avons in the United Kingdom.
Brazilian nationality law is based on both the principles of "jus soli" and of "jus sanguinis".
 As a general rule, any person born in Brazil acquires Brazilian nationality at birth, irrespective of status of parents.
 Nationality law is regulated by Article 12 of the Brazilian Federal Constitution.
