Social tension and issues began to arise in Romania under the Sima-Antonescu partnership, and Antonescu became increasingly frustrated with the Iron Guard, telling Sima that it was now "...time for order and legality" and that Legionnaires would "not [be] allowed to demand audiences with the Ministers whenever they want." Additionally, Sima had failed to win the total support of his German allies, who feared that the Legionnaires were unprepared to administer the country effectively. Infrastructure in Bucharest began to fail, and following a November earthquake, a number of deaths and the destruction of buildings in the capital further exposed the government's disorganization. By the end of 1940, prices fluctuated greatly and crops began to fail, producing 70% less food than the year prior. Frustration from citizens and Legionnaires fell on Sima, and Ion Zelea Codreanu, Corneliu Codreanu's father, referred to Sima as "a Satan, in whom the soul of Stelescu lives" (referencing the dissident Legionnaire Mihai Stelescu, who was said to have plotted to assassinate Corneliu Codreanu). Sima responded to dissent within the Iron Guard by placing a number of prominent Legionnaires under house arrest, including Corneliu Zelea Codreanu's brothers and father. Alongside a group of dissatisfied Legionnaires, the senior Codreanu occupied the Iron Guard's Bucharest headquarters, the Casa Verde, and attempted a putsch. A number of Legionnaires also called for Sima's assassination. A movement within the Iron Guard soon arose to clear the late Corneliu Zelea Codreanu of his treason charges, and his body was exhumed.
