Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Global Net Lease, Inc. (the "Company"), formerly known as American Realty Capital Global Trust, Inc., incorporated on July 13, 2011, is a Maryland corporation that elected and qualified to be taxed as a real estate investment trust ("REIT") for United States ("U.S.") federal income tax purposes beginning with the taxable year ended December 31, 2013. The Company operated as a non-traded REIT through June 1, 2015. On June 2, 2015 (the "Listing Date"), the Company listed its shares of common stock, $0.01 par value per share ("Common Stock") on the New York Stock Exchange ("NYSE") under the symbol "GNL" (the "Listing"). On February 28, 2017, the Company completed a reverse stock split of the Company’s Common Stock, OP Units and LTIP Units, at a ratio of 1-for-3 (the “Reverse Stock Split”). No OP Units were issued in connection with the Reverse Stock Split and the Company repurchased any fractional shares outstanding with cash. No payments were made in respect of any fractional OP Units. The Reverse Stock Split was applied to all of the Company’s outstanding shares of Common Stock and therefore did not affect any stockholder’s relative ownership percentage. As a result of the Reverse Stock Split, the number of outstanding shares of the Company’s Common Stock was reduced from 198.8 million to 66.3 million. In addition, at the market open on March 1, 2017, the Common Stock was assigned a new CUSIP number. All references made to share or per share amounts in the accompanying consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect this Reverse Stock Split. The Company was formed to primarily acquire a diversified portfolio of commercial properties, with an emphasis on sale-leaseback transactions involving single tenant net-leased commercial properties. As of March 31, 2017, the Company owned 312 properties consisting of 22.2 million rentable square feet, which were 100% leased, with a weighted average remaining lease term of 9.5 years. Based on original purchase price or acquisition value with respect to properties acquired in the Merger (as defined below), 49.5% of the Company's properties are located in the U.S. and the Commonwealth of Puerto Rico and 50.5% are located in Europe. The Company may also originate or acquire first mortgage loans secured by real estate. As of March 31, 2017, the Company did not own any mezzanine loans, preferred equity or securitized loans. On June 30, 2014, the Company completed its initial public offering ("IPO") after selling 57.4 million of its Common Stock, at a price of $30.00 per share, subject to certain volume and other discounts. In addition, the Company issued an additional 0.4 million shares pursuant to its dividend reinvestment program (the "DRIP"). On April 7, 2015, in anticipation of the Listing, the Company announced the suspension of the DRIP. On May 7, 2015, the Company filed a post-effective amendment to its registration statement on Form S-11 (File No. 001-37390) (as amended, the "Registration Statement") to deregister the unsold shares registered under the Registration Statement. The Company's DRIP was terminated effective December 9, 2016. In connection with the Listing, the Company offered to purchase up to 4.0 million shares of its Common Stock at a price of $31.50 per share (the “Tender Offer”). As a result of the Tender Offer, on July 6, 2015, the Company purchased approximately 4.0 million shares of its Common Stock at a price of $31.50 per share, for an aggregate amount of $125.0 million, excluding fees and expenses relating to the Tender Offer and including fractional shares repurchased thereafter. Substantially all of the Company's business is conducted through Global Net Lease Operating Partnership, L.P. (the "OP"), a Delaware limited partnership. At Listing, the OP had issued 603,219 units of limited partnership interests ("OP Units") to limited partners other than the Company, of which 487,252 OP Units were issued to Global Net Lease Advisors, LLC (the "Advisor") and 115,967 OP Units were issued to Moor Park Capital Partners LLP (the "Service Provider") (see Note 11 — Related Party Transactions). Subsequent to the Listing, all OP Units issued to the Advisor were transferred to individual investors. In accordance with the limited partnership agreement of the OP, a holder of OP Units has the right to convert OP Units, at the Company's option, for a corresponding number of shares of the Company's Common Stock or the cash value of those corresponding shares. The remaining rights of the limited partner interests are limited and do not include the ability to replace the general partner or to approve the sale, purchase or refinancing of the OP's assets. On September 2, 2016, 421,378 of the OP Units were converted into Common Stock, of which 305,411 were issued to individual members and employees of AR Global Investments, LLC (the successor business to AR Capital LLC "AR Global") and 115,967 were issued to the Service Provider. There were 181,841 OP Units outstanding that were held by parties other than the Company as of March 31, 2017, all of which were converted into Common Stock on April 3, 2017. The Company has retained the Advisor to manage the Company's affairs on a day-to-day basis. The properties are managed and leased by Global Net Lease Properties, LLC (the "Property Manager"). The Advisor, Property Manager and Global Net Lease Special Limited Partner, LLC (the "Special Limited Partner") are under common control with the parent of AR Capital Global Holdings, LLC (the "Sponsor"), as a result of which they are related parties. These related parties receive compensation and fees for various services provided to the Company. The Advisor has entered into a service provider agreement with the Service Provider, pursuant to which the Service Provider provides, subject to the Advisor's oversight, certain real estate related services, as well as sourcing and structuring of investment opportunities, performance of due diligence, and arranging debt financing and equity investment syndicates, solely with respect to investments in Europe. The Company and American Realty Capital Global Trust II, Inc. ("Global II"), an entity formerly sponsored by an affiliate of the Sponsor, entered into an agreement and plan of merger on August 8, 2016 (the "Merger Agreement"). On December 22, 2016, pursuant to the Merger Agreement, Global II merged with and into Mayflower Acquisition LLC (the "Merger Sub"), a Maryland limited liability company and wholly owned subsidiary of the Company, at which time the separate existence of Global II ceased and the Company became the parent of the Merger Sub (the "Merger"). In addition, pursuant to the Merger Agreement, American Realty Capital Global II Operating Partnership, L.P., a Delaware limited partnership and the operating partnership of Global II (the "Global II OP"), merged with the OP, with the OP being the surviving entity (the "Partnership Merger" and together with the Merger, the "Mergers"). As a result of the Mergers, the Company acquired the business of Global II, which immediately prior to the effective time of the Merger, owned a portfolio of commercial properties, including single tenant net-leased commercial properties two of which were located in the U.S., three of which were located in the United Kingdom and 10 of which were located in continental Europe (see Note 3 — Merger Transaction). The Company and Global II each were sponsored, directly or indirectly, by the Sponsor. The Sponsor and its affiliates provide or provided asset management services to the Company and Global II pursuant to written advisory agreements. In connection with the Merger Agreement, the Sponsor and its affiliates had the vesting of certain of their restricted interests in Global II and the Global II OP accelerated.
