The Beirut I electoral district covers four quartiers (neighbourhoods) of the Lebanese capital: Achrafieh, Saifi, Rmeil and Medawar.

It covered six neighbourhoods (quartiers) of the capital; Achrafieh, Medawar, Minet El Hosn, Port, Rmeil and Saifi.

[11] In a surprise move ahead of the 1964 general election, Camille Chamoun withdrew his candidates from Beirut I.

[13] During the 1968 general election the electoral district had 98,439 eligible voters, out of whom 28,631 voted (29.59 percent, the lowest turn-out of all constituencies).

[20] According to an article in Nahar newspaper published in May 2008, 2.24% of the registered voters of Beirut I were Protestants, 1.89% Shia Muslims and 0.28% Druze.

[20] Before the election a lot of attention was given to the race in Beirut I, as it was one of a handful of electoral districts where the outcome was difficult to predict on forehand.

[22] In November 2008, Tashnaq leaders met with a number of key personalities such as President Michel Suleiman, Prime Minister Fouad Siniora, Speaker Nabih Berri, Ministers Elias Murr, Tamam Salam and Tarek Mitri, Jean Kahwaji (Commander-in-Chief of the Lebanese Armed Forces), Sheikh Abdel Amir Kabalan, Maronite Patriarch Nasrallah Boutros Sfeir and Metropolitan Elias Audi.

[28] On March 8, 2009, Tashnaq leader Mekhitarian met with Saad Hariri and Michel Murr to discuss the upcoming election.

[29] On April 2, 2009, the Tashnaqs publicly stated that they would contest the elections in alliance with Michel Aoun, rejecting Hariri's offer.

[30] The Ramgavar and Hunchak parties were willing to contest on the March 14 list, but the Lebanese Forces also nominated an Armenian Catholic candidate, Richard Kouyoumjian.

[39] The Lebanese Forces, together with the Kataeb Party, Ramgavars and Michel Pharaon, and with support from Antoun Sehnaoui, fielded their list under the label "Beirut I".

[38][40] Michelle Tueni fielded a third list, "We Are Beirut", being joined by incumbent Future MP Serge Torsarkissian.

[39] For the Minorities seat the FPM fielded a Syriac Orthodox candidate, former Brigadier General Antoine Pano, whilst the Tueni list included Latin Catholic candidate Rafic Bazerji, an independent from a family historically close to the National Liberal Party.

[41][42] The eastern part of the capital was devastated by August 4 explosion in 2020 which strongly distanced the inhabitants of these neighborhoods from the long-running political powers which gave a significant increase in popularity for opposition candidates who were running in behalf of the 17 October Revolution.

[44] The Lebanese Forces and the Kataeb Party still had large population amongst Christian voters especially due to the Free Patriotic Movement's decline.

[46] The Lebanese Forces, together with the Hunchak Party and other independents, fielded their list under the label "Beirut, Nahno Laha".

[44] The Free Patriotic Movement again fielded a list with the Tashnag Party but without intention of creating a joint bloc in the Lebanese Parliament.
