In 1921, Sadoveanu was elected a full member of the Romanian Academy; he gave his reception speech in front of the cultural forum two years later, structuring it as a praise of Romanian folklore in general and folkloric poetry in particular.
At the time, he renewed his contacts with Viața Românească: with Garabet Ibrăileanu and several others, he joined its interwar nucleus, while the review often featured samples of his novels (some of which were originally published in full by its publishing venture).
His house was by then host to many cultural figures, among whom were writers Topîrceanu, Gala Galaction, Otilia Cazimir, Ionel and Păstorel Teodoreanu, and Dimitrie D. Pătrășcanu, as well as conductor Sergiu Celibidache.
He was also close to a minor socialist poet and short story author, Ioan N. Roman, whose work he helped promote, to the aristocrat and memoirist Gheorghe Jurgea-Negrilești, and to a satirist named Radu Cosmin.

Despite his health problems, Sadoveanu frequently traveled throughout Romania, notably visiting local sights which inspired his work: the Romanian Orthodox monasteries of Agapia and Văratec, and the Neamț Fortress.
After 1923, together with Topîrceanu, Demostene Botez and other Viața Românească affiliates, he also embarked on a series of hunting trips.
He was charmed in particular by the sights he discovered during a 1927 visit to the Transylvanian area of Arieș.
The same year, he also visited the Netherlands, which he reached by means of the Orient Express.
His popularity continued to grow: in 1925, 1929 and 1930 respectively, he published his critically acclaimed novels Venea o moară pe Siret..., Zodia Cancerului and Baltagul, and his 50th anniversary was celebrated at a national level.
In 1930, Sadoveanu, Topîrceanu and the schoolteacher T. C. Stan wrote and edited a series of primary school textbooks.

In 1926, after a period of indecision, Sadoveanu rallied with the People's Party, where his friend, the poet Octavian Goga, was a prominent activist.
He then rallied with Goga's own National Agrarian Party.
During the general election of 1927, he won a seat in the Chamber for Bihor County, in Transylvania, holding a seat in the Senate for Iași County after the 1931 suffrage.
Under Nicolae Iorga's National Peasants' Party cabinet of the period, Sadoveanu was President of the Senate.
The choice was motivated by his status as "a cultural personality".
Around that date, he was affiliated with the National Liberal Party-Brătianu, a right-wing party inside the liberal current, who stood in opposition to the main National Liberal group.
In parallel, he began contributing to the left-wing daily Adevărul.

Sadoveanu was by then affiliated with the Freemasonry, as first recorded by the organization in 1928, but was probably a member since 1926 or 1927.
Reaching the 33rd degree within the organization and overseeing the Masonic Lodge Dimitrie Cantemir of Iași, he was elected Grand Master of the National Union of Lodges in 1932, thus replacing the vacating George Valentin Bibescu.
There subsequently occurred a split between Bibescu and Sadoveanu's supporters, aggravated by their publicized conflict with a third group, that of Ioan Pangal—splits which ended after some three years, when Sadoveanu marginalized both of his opponents, without however earning legitimate recognition from the Grand Orient de France.
By 1934, he was recognized as Grand Master of the United Romanian Freemasonry, which regrouped all major local Lodges.
