, in April 1934 The September Junta was not homogeneous, and quickly a progressive wing, headed by
Marmaduke Grove and
Carlos Ibáñez del Campo, developed contacts with the
Comité Obrero Nacional and others labour organizations who advocated for Alessandri's return. This led to a
coup in January 1925, directed by Colonel Grove who handed out the power to General
Pedro Dartnell as interim president while waiting for Alessandri's return. Dartnell formed the
January Junta, before retroceding the power to Alessandri on March 20, 1925. Alessandri had
a new Constitution drafted, and approved by
plebiscite by 134,421 voters on August 30. The Constitution, which was promulgated on September 18, 1925, reinforced presidential powers over the legislative. Furthermore, Alessandri created a
Central Bank, initiating the first rupture with
laissez faire policies. His second government began with the support of left-wing and radical groups. However, this second group began to distance itself from the President. In March 1925, Alessandri's government repressed a demonstration, leading to the
Marusia massacre, soon followed by
La Coruña massacre. This break with the working classes caused him to try to maintain a right-wing-radical alliance until 1937, when it took a turn towards the left. In order to face the threats of a coup, Alessandri relied on the republican forces, entrusted with repressing any intent to revolt and never to get involved in politics. They were created shortly before Alessandri's return, as a consequence of the civil movement. They functioned in secret and then publicly, marching in a great parade May 7, 1933, in front of the President, who saluted them. They auto-disbanded in 1936, having considered their mission complete. The President asked the Parliament on several opportunities for the state of constitutional exception, resulting in illegal actions, such as the famous burning of the
Topaze Magazine issue No. 285, which depicted a caricature of Alessandri he considered offensive. That time was also marked by the appearance of new violent occurrences, such as the rural rebellion of Ránquil and their bloody repression, and the
Nazi-inspired
National Socialist Movement of Chile of
Jorge González von Marées. In the economic sphere, the recovery of the
crisis of 1929 was begun with the work of the Treasury Minister
Gustavo Ross, a pragmatic liberal who implemented a "towards in" approach to growth. With respect to nitrates, he dissolved
COSACH and created the
COVENSA (Corporation of Nitrate and Iodine Sale), a multi-faceted distributor and not a producer. He balanced the fiscal deficit with new taxes and resumed payment of the external debt, with losses for holders of Chilean bonds. When they reached a surplus, they focused on public works. The construction of the
National Stadium in Santiago, inaugurated in December 1938, stands out. The degree of Alessandri's responsibility in the 1938
Seguro Obrero massacre has been a subject of speculation. ==Public life after the presidency==
