Australia’s federal government moves its capital from Melbourne to

Canberra on May 9, 1927, with the opening of the Provisional Parliament House.

Ibn Saud finds himself increasingly at odds with the more religious elements of Nejd because of his association with Christian powers and his alleged complacence in regard to the British-protected regimes in Iraq and Transjordan, which remain the objects of Ikhwan desire for conquest.

The Ikhwan castigate him for introducing such innovations as telephones, automobiles, and the telegraph and for sending his son to a country of unbelievers (Egypt).

Having lost control of the Ikhwan by 1926, Ibn Saud endeavors to mollify them by submitting their accusations to the religious scholars (ulama).

In 1927...

Romanian political agitator Corneliu (Zelea) Codreanu, early exposed to anti-Jewish sentiments, had participated widely in anticommunist and anti-Jewish activities during his university years at Iasi, where in 1922 he had helped found the Association of Christian Students, which, from 1923 to 1927, he has affiliated with the League of National Christian Defense (LANC), headed by the anti-Jewish university professor A.C. Cuza.

Codreanu had been arrested and imprisoned in 1923 for threatening to kill "traitors"; arrested again on a murder charge in 1925, he had been acquitted.

In 1927, he breaks with LANC to form his Legion of the Archangel Michael, a fascist Christian-nationalist anti-Jewish organization, which will later call itself the Legion or Legionary Movement.

Liapchev generally is more lenient toward political opposition than Tsankov; the communists resurface in 1927 under cover of the labor-based Bulgarian Workers' Party, and an Independent Workers' Trade Union becomes the center of political activity by labor.

German philosopher Martin Heidegger, born in rural Meßkirch, Germany and raised a Roman Catholic, was the son of the sexton of the village church.

His family could not afford to send him to university, so he entered a Jesuit seminary.

After studying theology at the University of Freiburg from 1909 to 1911, he switched to philosophy.

Heidegger completed his doctoral thesis on psychologism in 1914, and in 1916 finished his venia legendi with a thesis on John Duns Scotus.

In the two years following, he worked first as an unsalaried Privatdozent, then served as a soldier during the final year of the Great War, working behind a desk and never leaving Germany.

After the war, he served as a salaried senior assistant to Edmund Husserl at the University of Freiburg until 1923, when he had been elected to an extraordinary Professorship in Philosophy at the University of Marburg.

His colleagues there include Rudolf Bultmann, Ernst Friedländer, Nicolai Hartmann, and Paul Natorp.

Heidegger's students at Marburg include Hans-Georg Gadamer, Hannah Arendt, Karl Löwith, Gerhard Krüger, Leo Strauss, Gunther (Stern) Anders, and Hans Jonas.

His best known book, Being and Time, is generally considered to be one of the most important philosophical works of the 20th century.

Although written quickly, and despite the fact that Heidegger never completed the project outlined in the introduction, it remains his most important work and will profoundly influence 20th-century philosophy, particularly existentialism, hermeneutics and deconstruction.

Austrian theoretical physicist Erwin Schrödinger had in January 1926 published in the Annalen der Physik the paper "Quantisierung als Eigenwertproblem" [tr.

Quantization as an Eigenvalue Problem] on wave mechanics and what is now known as the Schrödinger equation.

In this paper he had given a "derivation" of the wave equation for time independent systems, and showed that it gave the correct energy eigenvalues for the hydrogen-like atom.

This paper has been universally celebrated as one of the most important achievements of the twentieth century, and created a revolution in quantum mechanics, and indeed of all physics and chemistry.

he had submitted a second paper just four weeks later that solved the quantum harmonic oscillator, the rigid rotor and the diatomic molecule, and gives a new derivation of the Schrödinger equation.

A third paper in May had shown the equivalence of his approach to that of Heisenberg and given the treatment of the Stark effect.

A fourth paper in this most remarkable series showed how to treat problems in which the system changes with time, as in scattering problems.

These papers are the central achievement of his career and are at once recognized as having great significance by the physics community.

In 1927, he succeeds Max Planck at the Friedrich Wilhelm University in Berlin.

Yehoshua Hankin, the driving force of the PLDC, is another personage active in Jewish land acquisitions.

By dint of personal efforts beginning in 1890, he had secured the land on which Rehovot, Hadera, and the ICA settlements in the Galilee and elsewhere have been built, as well as most of the Jezreel Valley —sixty thousand hectares in all.

In 1927, Hankin presents the Jewish Agency for Israel with a twenty-year purchase plan for land acquisition,  a plan that will never be carried out in full.

During the First World War, Hankin had been exiled by the Turks to Anatolia.

Returning to Palestine, he soon resumed his work where he had left off.

In 1920, he concluded a deal with the Sursuk family of Beirut for purchase of sixty thousand dunams (sixty square kilometers) of land in the Jezreel Valley.

He negotiated for this land when he had in fact not a penny to finance the purchase.

The chairman of the Jewish National Fund, Nehemiah De Lieme, refused to pay for the land, arguing that it was beyond the budget of the Fund, but he was overruled by the Zionist organization and in particular Chaim Weizmann.

This tract became home to numerous new kibbutzim and other settlements, including Nahalal, Ginegar, Kfar Yehezkel, Geva, Ein Harod, Tel Yosef and Beit Alfa.

Half of this land was unirrigated and considered of low value, but the remainder contained about five hunddred Arab tenant farmers.

Radic had in July 1923 gone abroad to seek support for a Croatian peasant republic but returned disappointed to Zagreb in August 1924 and was imprisoned until July 1925.

Accepting the 1921 centralist constitution, however, he entered the government in 1925 but returns to opposition in 1927.

In an unexpected collaboration with Svetozar Pribicevic, a Serbian Democratic leader, he forms the peasant-democratic alliance that demands a federalist reorganization of the Kingdom of the Serbs, Croats, and Slovenes.

By summer 1926, former politicians, led by conservative José Sánchez Guerra, had been pressing the king to remove Primo de Rivera and restore constitutional government.

To demonstrate his public support, Primo de Rivera had ordered the UP to conduct a plebiscite in September.

Voters could endorse the regime or abstain.

About a third of those able to vote declined to go to the polls.

Nevertheless, buoyed by his victory, Primo de Rivera decides to create an entirely new political system.

On October 10, 1927, with the king in attendance, he opens a National Assembly.

Although they meet in the Cortes chamber, members of the regime-appointed assembly can only advise Primo de Rivera.

They have no legislative power.
