County Mayo in the context of "Knock, County Mayo"

Charles Cunningham Boycott (12 March 1832 – 19 June 1897) was an English land agent whose ostracism by his local community in Ireland gave the English language the term boycott. He had served in the British Army 39th Foot, which brought him to Ireland. After retiring from the army, Boycott worked as a land agent for Lord Erne, a landowner in the Lough Mask area of County Mayo.

In 1880, as part of its campaign for the Three Fs (fair rent, fixity of tenure, and free sale) and specifically in resistance to proposed evictions on the estate, local activists of the Irish National Land League encouraged Boycott's employees (including the seasonal workers required to harvest the crops on Lord Erne's estate) to withdraw their labour, and began a campaign of isolation against Boycott in the local community. This campaign included shops in nearby Ballinrobe refusing to serve him, and the withdrawal of services. Some were threatened with violence to ensure compliance.

Longford (Irish: An Longfort) is the county town of County Longford in Ireland. It had a population of 10,952 at the 2022 census. It is the biggest town in the county and about one third of the county's population lives there. Longford lies at the meeting of Ireland's N4 and N5 roads, which means that traffic travelling between Dublin and County Mayo, or north County Roscommon passes around the town. Longford railway station, on the Dublin-Sligo line, is used heavily by commuters.

Lough Mask (Irish: Loch Measca) is a limestone lake of about 83 km (32 sq mi) in Counties Mayo and Galway, Ireland, north of Lough Corrib. Lough Mask is the middle of the three lakes, which empty into the Corrib River, through Galway, into Galway Bay. Lough Carra flows into Lough Mask, which discharges through the Cong Canal and underground passages in the limestone bedrock of the district. The flows from the underground passages and the Cong Canal come together at the village of Cong to form the River Cong which flows into Lough Corrib.

Lough Mask is the fourth largest lake, by area, in Ireland and the sixth largest lake in the island of Ireland. The eastern half of Lough Mask is shallow and contains many islands. The other half (Upper Lough Mask) is much deeper, sinking to a long trench with depths in excess of 50 metres.Lough Mask has a mean depth of 15 m (49 ft), and a maximum depth of 58 m (190 ft). Its water volume of 1.3 km (1.1 million acre⋅ft) is the largest in the Republic of Ireland and the second largest on the island of Ireland (after Lough Neagh).

Ballinrobe (Irish: Baile an Róba, meaning 'town of the (river) Robe') is a town in County Mayo in Ireland. It is located on the River Robe, which empties into Lough Mask two kilometres to the west. As of the 2022 census, the population was 3,148. The town is in a civil parish of the same name.

Sand theft or unauthorised or illegal sand mining leads to a relatively unknown global example of natural and non-renewable resource depletion problem comparable in extent to global water scarcity. Beach theft is illegal removal of large quantities of sand from a beach leading to full or partial disappearance of the beach. In India, illegal sand mining is the country's largest organized criminal activity. Sand theft feeds the illegal sand trade, a black market estimated to be worth between $200B and $350B a year.

Lough Corrib (/lɒx ˈkɒrɪb/ lokh KORR-ib; Irish: Loch Coirib) is a lake in the west of Ireland. The River Corrib or Galway River connects the lake to the sea at Galway. It is the largest lake within the Republic of Ireland and the second largest on the island of Ireland (after Lough Neagh). It covers 176 km² and lies mostly in County Galway with a small area of its northeast corner in County Mayo.

The first canal on the island of Ireland was cut in the 12th century. Known as the Friar's Cut, it allowed boats to pass from Lough Corrib to the sea at Galway.

Connacht Irish (Irish: Gaeilge Chonnacht) is the dialect of the Irish language spoken in the province of Connacht. Gaeltacht regions in Connacht are found in Counties Mayo (notably Tourmakeady, Achill Island and Erris) and Galway (notably in parts of Connemara and on the Aran Islands). Connacht Irish is also spoken in the Meath Gealtacht Ráth Chairn and Baile Ghib. The dialects of Irish in Connacht are extremely diverse, with the pronunciation, forms and lexicon being different even within each county.

The Irish of South Connemara is often considered the "standard" Connacht Irish owing to the number of speakers however it is unique within Connacht and has a lot more idiomatic connection to extinct dialects in North Clare (for example "acab" instead of "acu" in the rest of Connacht). Words such as dubh and snámh tend to be pronounced with a Munster accent in South Connemara whereas in Joyce Country, Galway City and Mayo they are pronounced with the Ulster pronunciation. In addition to this the standard in Connacht would be to pronounce the words leo and dóibh as "leofa" and "dófa" however in South Connemara and Aran they are pronounced "leothab" and "dóib". Lexical and pronunciation differences exist within Mayo with Tourmakeady featuring an "í" sound in vowel endings much more commonly. In addition to this the lexicon of Dún Chaocháin to the east of Belmullet tends to be far more Ulster influenced than that of Eachléim (murlas vs ronnach) and there is a huge Ulster influence on the dialect of North Mayo in general owing to historic migration. The Irish of Eachréidh na Gaillimhe and Dúiche Sheoigheach tend to share more phonetic commonalities with neighbouring Mayo than with South Connemara.
