The Christian Peace Conference was an international organization based in Prague and founded in 1958 by Josef Hromádka, a pastor who had spent the war years in the United States, moving back to Czechoslovakia when the war ended.
 Hromádka was a member of the Bureau of the World Peace Council.
 He was not a Marxist, but the Christian Peace Conference often endorsed positions taken by Eastern bloc governments.
 It has been alleged to have received $210,000 from Soviet sources.
The Czech Corridor was a failed proposal during the Paris Peace Conference of 1919 in the aftermath of World War I.
 The proposal would have carved out an area of land to connect the Kingdom of Yugoslavia and Czechoslovakia.
 A different name often given is "Czech–Yugoslav Territorial Corridor".
 It is called the Czech Corridor, because representatives of Yugoslavia at the Peace Conference stated that they would prefer it be given to the Czechs.
 The proposal was rejected by the conference.
Eric Schultz is a senior advisor to former President Barack Obama and is the founder of Schultz Group.
 Schultz is a former White House Principal Deputy Press Secretary and special assistant to President Obama.
 Recognized by "Politico" as the strategist “White House officials turn to in a crisis to handle communications,” Schultz was originally hired at the White House in 2011 to respond to Congressional oversight investigations.
 After White House Deputy Press Secretary Josh Earnest replaced Jay Carney to become White House Press Secretary, Schultz was appointed White House Deputy Press Secretary.
 In this role, Schultz often diffuses "tensions with humor.
 But he can be relentless in pushing his message in both public and private conversations.”
 Former White House Communications Director Jen Psaki compared Schultz to fictional crisis manager Olivia Pope, "he's the person you want next to you in a foxhole when there's a crisis."
 At the end of President Obama's second term, former White House Senior Advisor Valerie Jarrett said of Schultz, “We’ve all grown to rely on his wise counsel" and that the President "trusts his sound judgement."

The Peace Conference of 1861 was a meeting of 131 leading American politicians in February 1861, at the Willard's Hotel in Washington, DC, on the eve of the American Civil War.
 The success of President Abraham Lincoln and the Republican Party in the 1860 presidential elections led to a flurry of political activity.
 In much of the South, elections were held to select delegates to special conventions to consider secession from the Union.
 In Congress, efforts were made in both the House of Representatives and the Senate to reach compromise over the issues relating to slavery that were dividing the nation.
 The conference was the final effort by the individual states to resolve the crisis.
 With the seven states of the Cotton South already committed to secession, the emphasis to preserve the Union peacefully focused on the eight slaveholding states representing the Upper and Border South, with the states of Virginia and Kentucky playing key roles.
A White House conference is a national meeting sponsored by the Executive Office of the President of the United States with the purpose of discussing an issue or topic of importance to the American public.
 Some last for one day while others last for several.
 Typical attendees of a White House conference include experts in the particular field, community leaders and citizens with an interest in the issue.
 The President usually speaks to a general session of the conference; the conference concludes by issuing a report to the President summarizing issues and making recommendations for executive or legislative action.
 The First Lady of the United States also sometimes hosts White House conferences.
 White House conferences are typically created by specific legislation.
