[14] He started publishing national history studies already as a student, winning prizes set by University Foundation "Carol I" for his work on the Romanian princes Radu cel Frumos and Vlad-Vodă Călugărul, as well as being the university laureate and winner of the important "Hillel" price for his work "Istoria breslelor la români" ("The History of the Romanian Guilds").

[15][16][17] Upon his graduation in 1903, Alexandru Lapedatu was offered an entry position as a clerk at the Library of the Romanian Academy, section for manuscripts, where he worked between 1903 and 1908; at the same time, he became a substitute professor at the Saint Sava National College in Bucharest.

[42] Descending from a family keeping "strong the awareness of the rights of the unbending man", remaining "tenacious in its aspirations", Alexandru Lapedatu participated already in his school years, as many of his generation, in Romanian protests and demonstrations like the ones in Iași, in solidarity with the authors of the Memorandum.

In January 1918 he co-founded in Odessa the National Committee of the Romanian Refugees from Austria-Hungary that elected him as president, moved to Iași and became a political platform bringing substantive contributions in preparing Romania for the peace negotiations.

[46][9][47] In 1920, Alexandru Lapedatu was nominated as member of the Coronation Commission to organize the festivities consecrating Ferdinand I as the King of all Romanians, formally closing the political process of the Union of Transylvania with Romania.

President of the Senate Alexandru Lapedatu joined the National Renaissance Front established by King Carol II of Romania (Royal Decree Nr.

4321 from 15 December 1938) as the only political organization legally allowed in the country; Carol II transformed the Front into the Party of the Nation (Royal Decree Nr.

Alexandru Lapedatu entered in some circumscriptions in Transylvania in an electoral cartel with the Peasants' Party obtaining a modest and ephemeral electoral success in the elections from 19 November 1946, when two candidates were elected: Lapedatu in Cluj and Vasile Netea in Satu Mare, in spite of the tremendous pressure and falsifications perpetrated by the so-called Bloc of Democratic Parties dominated by the Communists.

He soon recognized that the communist repression would prevail, but did not give up hope: on 30 September 1949, it was reported to the Securitate that Alexandru Lapedatu "believes in the future of the nation and in the capitulation of Russia and of communism".

The Romanian Government decided to move the State Treasury to Russia in two transports, delegating Alexandru Lapedatu to accompany the second one that included cultural goods.

Through this committee, Lapedatu connected with key political personalities in Romania and, thanks to the support from the French Ambassador, the Count of Saint-Aulaire, established contacts the Triple Entente's representatives.

On 6 / 19 October the Committee issued a Declaration, distributed to all political actors including King Ferdinand I, contesting the manifesto of Charles I of Austria proclaiming the federalization of the Empire and demanding that all territories inhabited by Romanians be united with Romania.

Experiencing the depressing installation of a German Mission in Iași as a consequence of the Treaty of Bucharest (1918), Alexandru Lapedatu published the paper "Chestiunea transilvană" ("The Transylvanian Issue") in Neamul Românesc, stating that the solution will be found when the situation of all nationalities will be addressed in the peace negotiations at the end of the war, expected to happen soon.

Under his leadership, the Transylvania Section of the Historical Monuments Commission executed in 1929–1948 more than 240 conservation and restoration projects, addressing Romanian heritage such as antiques Roman and Dacian vestiges, medieval stone churches and monasteries, wooden architecture, rear glass painted icons, the Hunedoara and Bran Castles, the Suțu Palace and the Filipescu House in Bucharest etc.

[82] He presented the statement of reasons for the law clarifying that in the united Romania, besides the Orthodox Church, the State recognized the following cults: Romanian Greek-Catholic (united), Catholic (of Latin, Greek and Armenian ritual), reformed (Calvin), evangelic-Lutheran, Unitarian, Mosaic, Muslim and finally Baptist (recognized only in Transylvania), each governed by a different legislation in the regions coming from Russia, Austria, Hungary, Bulgaria respectively the Kingdom of Romania.

Since the two exceptions mentioned in the Constitution were no more in the position to challenge State prerogatives, it was now possible for Alexandru Lapedatu to submit to the Parliament, after animated consultations and debates, a project that obtained almost the unanimity of votes both in the Chamber of Deputy and in the Senate; it was adopted on 22 April 1928 and remained in power until 1948.

In 2019, a double monument dedicated to the Lapedatu brothers was unveiled under the aegis of the Romanian Academy, the National Bank of Romania and the City of Brașov.
